Part Details:

Complete Quad, 16-Bit, High Accuracy, Serial Input, ±5 V DAC AD5765 FEATURES GENERAL DESCRIPTION Complete quad, 16-bit digital-to-analog converter (DAC) The AD5765 is a quad, 16-bit, serial input, bipolar voltage Programmable output range: ±4.096 V, ±4.201 V, or ±4.311 V output, digital-to-analog converter (DAC) that operates from ±1 LSB maximum INL error, ±1 LSB maximum DNL error supply voltages of ±4.75 V to ±5.25 V. The nominal full-scale Low noise: 70 nV/Hz output range is ±4.096 V. The AD5765 provides integrated Settling time: 10 s maximum output amplifiers, reference buffers, and proprietary power- Integrated reference buffers up/power-down control circuitry. The part also features a On-chip die temperature sensor digital I/O port, which is programmed via the serial interface. Output control during power-up/brownout The part incorporates digital offset and gain adjustment Programmable short-circuit protection registers per channel. Simultaneous updating via LDAC The AD5765 is a high performance converter that offers Asynchronous CLR to zero code guaranteed monotonicity, integral nonlinearity (INL) of ±1 LSB, Digital offset and gain adjustment low noise, and 10 s settling time. During power-up (when the Logic output control pins supply voltages are changing), the outputs are clamped to 0 V DSP-/microcontroller-compatible serial interface via a low impedance path. Temperature range: -40°C to +105°C iCMOS® process technology1 The AD5765 uses a serial interface that operates at clock rates of up to 30 MHz and is compatible with DSP and microcontroller APPLICATIONS interface standards. Double buffering allows the simultaneous Industrial automation updating of all DACs. The input coding is programmable to either Open-/closed-loop servo control a twos complement or an offset binary format. The asynchronous Process control clear function clears all DAC registers to either bipolar zero or zero Data acquisition systems scale, depending on the coding used. The AD5765 is ideal for both Automatic test equipment closed-loop servo control and open-loop control applications. The Automotive test and measurement AD5765 is available in a 32-lead TQFP and offers guaranteed speci- High accuracy instrumentation fications over the -40°C to +105°C industrial temperature range.
