32-Channel 14-bit Bipolar Voltage-Output DAC

The AD5532B is a 32-channel, bipolar, voltage-output, 14-bit DAC with an additional infinite sample-and-hold mode. The device is operated with AVCC = +5V±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 REFIN as well as an offset voltage on OFFSIN. It is available in a 74-lead 12mm x 12mm CSPBGA package.

Also available is the AD5533B, which is specified in the sample and hold mode only and is the same part but without the DAC mode of operation.

The AD5532B is an improved spec version of the existing AD5532.

Product Highlights

* 32-channel, 14-bit DAC in one package, guaranteed

monotonic.

* The AD5532B is available in a 74-lead CSPBGA with a body

size of 12 mm × 12 mm.

* In infinite sample-and-hold mode, a total unadjusted error of

±2.5 mV is achieved by laser-trimming on-chip resistors.
