GENERAL DESCRIPTION
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 guar-
anteed 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 asynchro-
nous 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 appli-
cations. 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.
