Temperature Range –40C to +85C 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 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 В± 5%, DVCC = +2.7 V …
