DESCRIPTION
The DAC7613 is a 12-bit, voltage output digital-to-
analog converter with guaranteed 12-bit monotonic
performance over the specified temperature range.
The DAC7613 accepts a 12-bit parallel input data, has
double-buffered DAC input logic and provides a
readback mode of the internal input register. An asyn-
chronous reset clears all registers to a mid-scale code
of 800H or to a zero-scale of 000H. The DAC7613 can
operate from a single +5V supply or from +5V and
–5V supplies.
Low power and small size makes the DAC7613 ideal
for data acquisition systems and closed-loop servo-
control. The DAC7613 is available in a plastic
SSOP-24 package, and offers guaranteed specifica-
tions over the –40°C to +85°C temperature range.
