The AD5532 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.

Tools & Simulations
Precision DAC Error Budget Tool
The Precision DAC Error Budget Tool is a web application that calculates the DC Accuracy of precision DAC signal chains. It shows how the static errors accumulate throughout your signal chain to quickly evaluate the design tradeoffs. Calculations include the DC errors introduced by Voltage References, Operation Amplifiers and Precision DACs.
