The AD5764 is a quad, 16-bit, serial input, bipolar voltage output DAC that operates from supply voltages of ±11.4 V to ±16.5 V. Nominal full-scale output range is ±10 V. The AD5764 provides integrated output amplifiers, reference buffers, and proprietary power-up/power-down control circuitry. The part also features a digital I/O port that is programmed via the serial interface. The part incorporates digital offset and gain adjust registers per channel.

The AD5764 is a high performance converter that offers guaranteed monotonicity, integral nonlinearity (INL) of ±1 LSB, low noise, and 10 μs settling time. During power-up (when the supply voltages are changing), VOUTx is clamped to 0 V via a low impedance path.

The AD5764 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 the data register to either bipolar zero or zero scale depending on the coding used. The AD5764 is ideal for both closed-loop servo control and open-loop control applications. The AD5764 is available in a 32-lead TQFP, and offers guaranteed specifications over the −40°C to +85°C industrial temperature range. See Figure 1 for the functional block diagram.
