SBAS234 – FEBRUARY 2002

16-Bit, Dual Voltage Output

DIGITAL-TO-ANALOG CONVERTER

DESCRIPTION

FEATURES

ꢀ LOW POWER: 4mW

The DAC7632 is a 16-bit, dual channel, voltage output,

Digital-to-Analog Converter (DAC) which provides 15-bit

monotonic performance over the specified temperature range.

The device accepts 24-bit serial input data, has double-

buffered DAC input logic (allowing simultaneous update of

both DACs), and provides a serial data output for daisy-

chaining multiple devices. A programmable asynchronous

reset clears all registers to a mid-scale code of 8000_Hor to

a zero-scale code of 0000_H. The DAC7632 can operate from

a single +5V supply or from +5V and –5V supplies, providing

an output range of 0V to +2.5V or –2.5V to +2.5V, respec-

tively.

ꢀ UNIPOLAR OR BIPOLAR OPERATION

ꢀ SETTLING TIME: 10µs to ±0.003% FSR

ꢀ 15-BIT LINEARITY AND MONOTONICITY:

–40°C to +85°C

ꢀ PROGRAMMABLE RESET TO MID-SCALE

OR ZERO-SCALE

ꢀ DOUBLE-BUFFERED DATA INPUTS

APPLICATIONS

Low power and small size per DAC make the DAC7632

ideal for industrial process control, data acquisition sys-

tems, and closed-loop servo-control. The DAC7632 is avail-

able in an LQFP-32 package and specified over a –40°C to

+85°C temperature range.
