GENERAL DESCRIPTION
The AD5532B is a 32-channel, voltage output, 14-bit DAC with
an additional precision infinite sample-and-hold mode. The
selected DAC register is written to via the 3-wire serial inter-
face and V
contents of the DAC register. DAC selection is accomplished via
address bits A0–A4. The output voltage range is determined by
the offset voltage at the OFFS_IN pin and the gain of the
output amplifier. It is restricted to a range from V
V
The device is operated with AV
to +5.25 V, V
and requires a stable 3 V reference on REF_IN as well as an
offset voltage on OFFS_IN.

An AD780 provides the 3 V refer- ence for the AD5532B, and for the AD5541 16-bit DAC. A simple 3-wire serial interface is used to write to the AD5541. Because the AD5541 has an output resistance of 6 ...
