DESCRIPTION

The DAC7631 is a serial input, 16-bit, voltage out-

put Digital-to-Analog Converter (D/A) with guaran-

teed 15-bit monotonic performance over the –40

°C to

+85

°C temperature range. An asynchronous reset clears

all registers to either mid-scale (8000H) or zero-scale

(0000H), selectable via the RESETSEL pin. The de-

vice can be powered from a single +5V supply or from

dual +5V and –5V supplies.

Low power and small size makes the DAC7631 ideal

for process control, data acquisition systems, and

closed-loop servo-control. The device is available in a

SSOP-20 package, and is guaranteed over the

–40

°C to +85°C temperature range.
