com Preliminary Technical Data FEATURES Complete Dual, 16-Bit, High Accuracy, Serial Input, Bipolar Voltage Output DACs AD5762R GENERAL DESCRIPTION The AD5762R is a dual, 16-bit, serial input, bipolar voltage output digital-to-analog converter that operates from supply voltages of ±11.
4 V up to ±16.
5 V.
Nominal full-scale output range is ±10 V.
The AD5762R provides integrated output amplifiers, reference buffers and proprietary power-up/powerdown control circuitry.
The parts also feature a digital I/O port, which is programmed via the serial interface and an analog temperature sensor.
The part incorporates digital offset and gain adjust registers per channel.
The AD5762R is a high performance converter that offers guaranteed monotonicity, integral nonlinearity (INL) of ±1 LSB, low noise, and 10 µs settling time.
The AD5762R includes an on-chip 5 V reference with a reference tempco of 10 ppm/°C maximum.
During power-up (when the supply voltages are changing), VOUT is clamped to 0 V via a low impedance path.
The AD5762R uses a serial interface that operates at clock rates of up to 30 MHz and is compatible with DSP and microcontroller interface standards.
Double buffering allows the simultaneous updating of all DACs.
The input coding is programmable to either twos complement or offset binary formats.
The asynchronous clear function clears all DAC registers to either bipolar zero or zero scale depending on the coding used.
The AD5762R is ideal for both closed-loop servo control and open-loop control applications.
The AD5762R is available in a 32-lead TQFP, and offers guaranteed specifications over the −40°C to +85°C industrial temperature range.
See Figure 1, the functional block diagram.
