The ADC08060 is a low-power, 8-bit, monolithic analog-to-digital converter with an on-chip track-and-hold circuit. Optimized for low cost, low power, small size and ease of use, this product operates at conversion rates of 20 MSPS to 70 MSPS with outstanding dynamic performance over its full operating range while consuming just 1.3 mW per MHz of clock frequency. That's just 78 mW of power at 60 MSPS. Raising the PD pin puts the ADC08060 into a Power Down mode where it consumes just 1 mW. The unique architecture achieves 7.5 Effective Bits with 25 MHz input frequency. The excellent DC and AC characteristics of this device, together with its low power consumption and single +3V supply operation, make it ideally suited for many imaging and communications applications, including use in portable equipment. Furthermore, the ADC08060 is resistant to latch-up and the outputs are short-circuit proof. The top and bottom of the ADC08060's reference ladder are available for connections, enabling a wide range of input possibilities. The digital outputs are TTL/CMOS compatible with a separate output power supply pin to support interfacing with 3V or 2.5V logic. The output coding is straight binary and the digital inputs (CLK and PD) are TTL/CMOS compatible. The ADC08060 is offered in a 24-lead plastic package (TSSOP) and is specified over the industrial standard range.

LM27966 is a highly integrated charge-pump-based display LED driver from National. The device can drive up to 6 LEDs in parallel with a total output current of 180mA. Regulated internal current sources deliver excellent current and brightness matching in all LEDs. The LED driver current sources are split into two independently controlled groups. The primary group, which can be configured with 4 or 5 LEDs, can be used to backlight the main phone display. An additional, independently controlled led driver is provided for driving an indicator or other general purpose LED function. The LM27966 has an I2C compatible interface that allows the user to independently control the brightness on each bank of LEDs. The device provides excellent efficiency without the use of an inductor by operating the charge pump in a gain of 3/2, or in Pass-Mode. The proper gain for maintaining current regulation is chosen, based on LED forward voltage, so that efficiency is maximized over the input voltage range. The LM27966 is available in National’s small 24-pin Lead- less Leadframe Package (LLP-24).

The LP2954/LP2954A is a 5V micropower voltage regulator with very low quiescent current (90 µA typical at 1 mA load) and very low dropout voltage (typically 60 mV at light loads and 470 mV at 250 mA load current). The quiescent current increases only slightly at dropout (120 µA typical), which prolongs battery life. The LP2954 with a fixed 5V output is available in the three- lead TO-220 and TO-263 packages. The adjustable LP2954 is provided in an 8-lead surface mount, small outline pack- age. The adjustable version also provides a resistor network which can be pin strapped to set the output to 5V. Reverse battery protection is provided. The tight line and load regulation (0.04% typical), as well as very low output temperature coefficient make the LP2954 well suited for use as a low-power voltage reference. Output accuracy is guaranteed at both room temperature and over the entire operating temperature range.

The LM320L/LM79LXXAC dual marked series of 3-terminal negative voltage regulators features fixed output voltages of −5V, −12V, and −15V with output current capabilities in excess of 100mA. These devices were designed using the latest computer techniques for optimizing the packaged IC thermal/electrical performance. The LM79LXXAC series, even when combined with a minimum output compensation capacitor of 0.1µF, exhibits an excellent transient response, a maximum line regulation of 0.07% VO/V, and a maximum load regulation of 0.01% VO/mA. The LM320L/LM79LXXAC series also includes various self-protection circuitries. Although designed primarily as fixed voltage regulators, these devices may be combined with simple external circuitry for boosted and/or adjustable voltages and currents. The LM79LXXAC series is available in multiple package options. The LM320L series is available in the 3-lead TO-92 package. The LM137L series provides an output voltage range from 1.2V to 47V.

The LM193 series consists of two independent precision voltage comparators with an offset voltage specification as low as 2.0 mV max for two comparators which were designed specifically to operate from a single power supply over a wide range of voltages. Operation from split power supplies is also possible and the low power supply current drain is independent of the magnitude of the power supply voltage. These comparators also have a unique characteristic in that the input common-mode voltage range includes ground, even though operated from a single power supply voltage. Application areas include limit comparators, simple analog to digital converters; pulse, squarewave and time delay generators; wide range VCO; MOS clock timers; multivibrators and high voltage digital logic gates. The LM193 series was designed to directly interface with TTL and CMOS. When operated from both plus and minus power supplies, the LM193 series will directly interface with MOS logic where their low power drain is a distinct advantage over standard comparators.

The LM2796 is a charge-pump based white-LED driver that is ideal for mobile phone display backlighting. It can drive up to 7 LEDs in parallel with up to 20mA through each LED. Regulated internal current sources deliver excellent current and brightness matching in all LEDs. The LED-driver current sources are split into two independently controlled groups. The primary group (4 LEDs) can be used to backlight the main phone display. The second group (3 LEDs) can be used to backlight a secondary display or to provide other lighting features (keypad LEDs, for example). Brightness of the two groups can be adjusted independently with pulse- width modulated (PWM) digital signals. The LM2796 works off an extended Li-Ion input voltage range (2.7V to 5.5V). Voltage boost is achieved with a high- efficiency 3/2x-gain charge pump. The LM2796 is available in National’s chip-scale 18-bump micro SMD package.
