GENERAL DESCRIPTION
The AD5763 is a dual, 16-bit, serial input, bipolar voltage
output digital-to-analog converter (DAC) that operates from
supply voltages of ±4.75 V up to ±5.25 V. The nominal full-
scale output range is ±4.096 V. The AD5763 provides integrated
output amplifiers, reference buffers, and proprietary power-up/
power-down control circuitry. The part also features a digital
I/O port, which is programmed via the serial interface. The part
incorporates digital offset and gain adjust registers per channel.
The AD5763 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), the outputs are clamped to 0 V
via a low impedance path.
The AD5763 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 AD5763 is ideal
for both closed-loop servo control and open-loop control appli-
cations. The AD5763 is available in a 32-lead TQFP, and offers
guaranteed specifications over the −40°C to +105°C industrial
temperature range. Figure 1 contains a functional block diagram
of the AD5763.
