National Semiconductor DS2003/DS9667/DS2004 High Current/Voltage Darlington Drivers handbook(1)
The DS2003, DS9667, and DS2004 are comprised of seven high voltage, high current NPN Darlington transistor pairs. All units feature common emitter, open collector outputs. To maximize their effectiveness, these units contain suppression diodes for inductive loads and appropriate emitter base resistors for leakage. The DS2003, DS9667 has a series base resistor to each Darlington pair, thus allowing operation directly with TTL or CMOS operating at supply voltages of 5.0V. The DS2004 has an appropriate input resistor to allow direct operation from CMOS or PMOS outputs operating from supply voltages of 6.0V to 15V. The DS2003, DS9667, DS2004 offer solutions to a great many interface needs, including solenoids, relays, lamps, small motors, and LEDs. Applications requiring sink currents beyond the capability of a single output may be accommodated by paralleling the outputs.

National Semiconductor DAC1218/DAC1219 12-Bit Binary Multiplying D/A Converter handbook
The DAC1218 and DAC1219 are 12-bit binary 4-quadrant multiplying D to A converters. The linearity, differential non-linearity, and monotonicity specifications for these converters are all guaranteed over temperature. In addition, these parameters are specified with standard zero and full-scale adjustment procedures as opposed to the impractical best fit straight line guarantee. This level of precision is achieved though the use of an advanced silicon-chromium (SiCr) R-2R resistor ladder network. This type of thin-film resistor eliminates the parasitic diode problems associated with diffused resistors and allows the applied reference voltage to range from -25V to 25V, independent of the logic supply voltage. CMOS current switches and drive circuitry are used to achieve low power consumption (20 mW typical) and minimize output leakage current errors (10 nA maximum). Unique digital input circuitry maintains TTL compatible input threshold voltages over the full operating supply voltage range. The DAC1218 and DAC1219 are direct replacements for the AD7541 series, AD7521 series, and AD7531 series with a significant improvement in the linearity specification. In applications where direct interface of the D to A converter to a microprocessor bus is desirable, the DAC1208 and DAC1230 series eliminate the need for additional components.

The DAC101S101 is a full-featured, general purpose 10-bit voltage-output digital-to-analog converter (DAC) that can operate from a single +2.7V to 5.5V supply and consumes just 175 µA of current at 3.6 Volts.
National Semiconductor DAC1006/DAC1007/DAC1008 mP Compatible Double-Buffered D to A Converters handbook
The DAC1006, DAC1007, and DAC1008 are advanced CMOS-Si-Cr 10-, 9-, and 8-bit accurate multiplying DACs designed to interface directly with the 8080, 8048, 8085, Z-80, and other popular microprocessors. These DACs appear as a memory location or an I/O port to the microprocessor, and no interfacing logic is needed. When combined with an external amplifier and voltage reference, these devices can be used as standard D-A converters and are particularly attractive for multiplying applications (such as digitally controlled gain blocks) because their linearity error is essentially independent of the voltage reference. They are also attractive in audio signal processing equipment as audio gain controls or programmable attenuators, combining high-quality audio signal processing with digitally based systems under microprocessor control. All of these DACs are double-buffered and can load all 10 bits or two 8-bit bytes, with the data format being left justified. The analog section of these DACs is essentially the same as that of the DAC1020. The DAC1006 series are the 10-bit members of a family of microprocessor-compatible DACs (MICRO-DACs). For applications requiring other resolutions, the DAC0830 series (8 bits) and the DAC1208 and DAC1230 (12 bits) are available alternatives.
National Semiconductor DAC0890 Dual 8-bit mP-Compatible Digital-to-Analog Converter handbook
The DAC0890 is a complete dual 8-bit voltage output digital-to-analog converter that can operate on a single 5V supply. It includes on-chip output amplifiers, precision bandgap voltage reference, and full microprocessor interface. Each DAC0890 output amplifier has two externally selectable output ranges, 0V to 2.55V and 0V to 10.2V. The amplifiers are internally trimmed for offset and full-scale accuracy and therefore require no external user trims. The DAC0890 is supplied in a 20-pin ceramic DIP package.
National Semiconductor DAC088S085 8-Bit Micro Power OCTAL Digital-to-Analog Converter with Rail-to-Rail Outputs handbook
The DAC088S085 is a fully featured, general purpose OCTAL 8-bit voltage-output digital-to-analog converter (DAC) that can operate from a single +2.7V to +5.5V supply and con- sumes 1.95 mW at 3V and 4.85 mW at 5V. The DAC088S085 is packaged in a 16-lead LLP package and a 16-lead TSSOP package. The LLP package makes the DAC088S085 the smallest OCTAL DAC in its class. The on-chip output ampli- fiers allow rail-to-rail output swing and the three wire serial interface operates at clock rates up to 40 MHz over the entire supply voltage range. Competitive devices are limited to 25 MHz clock rates at supply voltages in the 2.7V to 3.6V range. The serial interface is compatible with standard SPI™, QSPI, MICROWIRE and DSP interfaces. The DAC088S085 also of- fers daisy chain operation where an unlimited number of DAC088S085s can be updated simultaneously using a single serial interface.
National DAC0854 handbook
The DAC0854 is a complete quad 8-bit voltage-output digital-to-analog converter that can operate on a single 5V supply. It includes on-chip output amplifiers, internal voltage reference, and a serial microprocessor interface. By combining in one package the reference, amplifiers, and conversion circuitry for four D/A converters, the DAC0854 minimizes wiring and parts count and is hence ideally suited for applications where cost and board space are of prime concern. The DAC0854 also has a data readback function, which can be used by the microprocessor to verify that the desired input word has been properly latched into the DAC0854’s data registers. The data readback function simplifies the design and reduces the cost of systems which need to verify data integrity. The logic comprises a MICROWIRETM-compatible serial interface and control circuitry. The interface allows the user to write to any one of the input registers or to all four at once. The latching registers are double-buffered, consisting of 4 separate input registers and 4 DAC registers. Double buffering allows all 4 DAC outputs to be updated simultaneously. The four reference inputs allow the user to configure the system to have a separate output voltage range for each DAC. The output voltage of each DAC can range between 0...

National Semiconductor DAC0830/DAC0832 8-Bit P Compatible Double-Buffered D to A Converters handbook
The DAC0830/DAC0832 8-Bit µP Compatible, Double-Buffered D to A Converters. The DAC0830 is an advanced CMOS/Si-Cr 8-bit multiplying DAC designed to interface directly with the 8080, 8048, 8085, Z80®, and other popular microprocessors. A deposited silicon-chromium R-2R resistor ladder network divides the reference current and provides the circuit with excellent temperature tracking characteristics (0.05% of Full Scale Range maximum linearity error over temperature). The cir- cuit uses CMOS current switches and control logic to achieve low power consumption and low output leakage current errors. Special circuitry provides TTL logic input volt- age level compatibility. Double buffering allows these DACs to output a voltage corresponding to one digital word while holding the next digital word. This permits the simultaneous updating of any number of DACs. The DAC0830 series are the 8-bit members of a family of microprocessor-compatible DACs (MICRO-DAC™).
