GENERAL DESCRIPTION
The AD5765 is a quad, 16-bit, serial input, bipolar voltage
output, digital-to-analog converter (DAC) that operates from
supply voltages of ±4.75 V to ±5.25 V. The nominal full-scale
output range is ±4.096 V. The AD5765 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 adjustment
registers per channel.
The AD5765 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), the outputs are clamped to 0 V
via a low impedance path.
The AD5765 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 a twos complement or an offset binary format. The
asynchronous clear function clears all DAC registers to either
bipolar zero or zero scale, depending on the coding used. The
AD5765 is ideal for both closed-loop servo control and open-
loop control applications. The AD5765 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 AD5765.

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, allowing dramatic reductions in power consumption and
package size and increased ac and dc performance.
