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/power-

down 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.

1 For analog systems designers within industrial/instrumentation equipment

OEMs who need high performance ICs at higher voltage levels, iCMOS is a

technology platform that enables the development of analog ICs capable of

30 V and operating at ±15 V supplies while allowing dramatic reductions in

power consumption and package size, and increased AC and DC

performance.
