DESCRIPTION
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_H or 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.
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.
