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 (8000
H
) or zero-scale
(0000
H
), 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.
