Voltage-Output DAC

Voltage-Output DAC

GENERAL DESCRIPTION
The AD5532 is a 32-channel voltage-output 14-bit DAC with
an additional infinite sample-and-hold mode. The selected DAC
register is written to via the 3-wire serial interface and 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
and requires a stable +3 V reference on REF_IN as well as an
offset voltage on OFFS_IN.
