GENERAL DESCRIPTION

The AD55321 is a 32-channel, 14-bit voltage-output DAC with

an additional infinite sample-and-hold mode. The selected

DAC register is written to via the 3-wire serial interface; VOUT

for this DAC is then updated to reflect the new 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 VSS + 2 V to VDD – 2 V because of

the headroom of the output amplifier.

The device is operated with AVCC = 5 V ± 5%; DVCC = 2.7 V to

5.25 V; VSS = −4.75 V to −16.5 V; and VDD = 8 V to 16.5 V. The

AD5532 requires a stable 3 V reference on REF_IN as well as an

offset voltage on OFFS_IN.
