LINEAR TECHNOLOGY LTC2606/LTC2616/LTC2626 handbook
The LTC2606/LTC2616/LTC2626 are 16-/14-/12-bit rail-to-rail voltage output DACs with I2C interface. They have built-in high-performance output buffers and are guaranteed monotonic. These parts establish new board-density benchmarks for 16- and 14-bit DACs and advance performance standards for output drive and load regulation in single-supply, voltage-output DACs. The parts use a 2-wire, I2C compatible serial interface. The LTC2606/LTC2616/LTC2626 operate in both the standard mode (clock rate of 100kHz) and the fast mode (clock rate of 400kHz). An asynchronous DAC update pin (LDAC) is also included. The LTC2606/LTC2616/LTC2626 incorporate a power-on reset circuit. During power-up, the voltage outputs rise less than 10mV above zero scale; and after power-up, they stay at zero scale until a valid write and update take place. The power-on reset circuit resets the LTC2606-1/LTC2616-1/LTC2626-1 to midscale. The voltage outputs stay at midscale until a valid write and update take place.
LINEAR TECHNOLOGY LTC1864/LTC1865 handbook
The LTC ®1864/LTC1865 are 16-bit A/D converters that are offered in MSOP and SO-8 packages and operate on a single 5V supply. At 250ksps, the supply current is only 850µA. The supply current drops at lower speeds because the LTC1864/LTC1865 automatically power down between conversions. These 16-bit switched capacitor successive approximation ADCs include sample-and-holds. The LTC1864 has a differential analog input with an adjustable reference pin. The LTC1865 offers a software- selectable 2-channel MUX and an adjustable reference pin on the MSOP version. The 3-wire, serial I/O, small MSOP or SO-8 package and extremely high sample rate-to-power ratio make these ADCs ideal choices for compact, low power, high speed systems. These ADCs can be used in ratiometric applications or with external references. The high impedance analog inputs and the ability to operate with reduced spans down to 1V full scale, allow direct connection to signal sources in many applications, eliminating the need for external gain stages.

LINEAR TECHNOLOGY LTC1603 handbook
The LTC ®1603 is a 250ksps, 16-bit sampling A/D con- verter that draws only 220mW from ±5V supplies. This high performance device includes a high dynamic range sample-and-hold, a precision reference and a high speed parallel output. Two digitally selectable power shutdown modes provide power savings for low power systems.
LINEAR TECHNOLOGY LT1638/LT1639 handbook
LT1638/LT1639 are super micro power rail-to-rail input and output operational amplifiers with a frequency of 1.2MHz and a slew rate of 0.4V/µs. They operate with inputs above V+, have low power consumption, high output current, etc. They are suitable for portable instrumentation, sensor conditioning, battery monitoring, micro power active filters, 4mA to 20mA transmitters, etc.
LINEAR TECHNOLOGY LT1949 handbook
The LT ®1949 is a fixed frequency step-up DC/DC converter with a 1A, 0.5Ω internal switch. Capable of generating 10V at 175mA from a 3.3V input, the LT1949 is ideal for generating bias voltages for large screen LCD panels.
LINEAR TECHNOLOGY LT1785/LT1785A/LT1791/LT1791A handbook
The LT1785/LT1791 are half-duplex and full-duplex differential bus transceivers for RS485 and RS422 applications which feature on-chip protection from overvoltage faults on the data transmission lines. Receiver input and driver output pins can withstand voltage faults up to ±60V with respect to ground with no damage to the device. Faults may occur while the transceiver is active, shut down or powered off. Data rates to 250kbaud on networks of up to 128 nodes are supported. Controlled slew rates on the driver outputs control EMI emissions and improve data transmission integrity on improperly terminated lines. Drivers are specified to operate with inexpensive cables as low as 72Ω characteristic impedance. The LT1785A/LT1791A devices have “fail-safe” receiver inputs to guarantee a receiver output high for shorted, open or inactive data lines. On-chip ESD protection eliminates need for external protection devices. The LT1785/LT1785A are available in 8-lead DIP and SO packages and the LT1791/LT1791A in 14-lead DIP and SO packages.
LINEAR LTC1657/LTC1657L handbook
The LTC1657/LTC1657L are complete single supply, rail-to-rail voltage output, 16-bit digital-to-analog converters (DAC) in a 28-pin SSOP or PDIP package. They include a rail-to-rail output buffer amplifier, an internal reference and a double buffered parallel digital interface. The LTC1657/LTC1657L have separate reference input pins that can be driven by an external reference. The full-scale output can be 1 or 2 times the reference voltage depending on how the X1/X2 pin is connected. The LTC1657 operates from a 4.5V to 5.5V supply and has an onboard 2.048V reference. The LTC1657L operates from a 2.7V to 5.5V supply and has an onboard 1.25V reference. The LTC1657/LTC1657L are similar to Linear Technology Corporation’s LTC1450/LTC1450L 12-bit VOUT DAC family, allowing an upgrade path. They are the only buffered 16-bit parallel DACs in a 28-lead SSOP package and include an onboard reference for stand alone performance.
LINEAR TECHNOLOGY LT1027 handbook
The LT1027 is a precision reference voltage from Linear Technology Corporation that features ultra-low drift, superior accuracy, excellent line and load regulation, and low output impedance at high frequency. This device is intended for use in 12- to 16-bit A/D and D/A systems where demanding accuracy requirements must be met without the use of power hungry, heated substrate references. The fast settling output recovers quickly from load transients such as those presented by A/D converter reference inputs. The LT1027 brings together both outstanding accuracy and temperature coefficient specifications. The LT1027 reference is based on LTC's proprietary advanced subsurface Zener bipolar process which eliminates noise and stability problems associated with surface breakdown.
