32-Channel 14-Bit bipolar DAC with High Speed 3-Wire Serial Interface

The AD5532HS is a 32-channel bipolar voltage-output 14-bit DAC with a high-speed serial interface and is packaged in a tiny 12x12 mm CSPBGA. The selected DAC register is written to via the 3-wire interface. The serial interface operates at clock rates up to 30 MHz and is compatible with DSP and microcontroller interface standards. The output voltage range is 0 V to 5 V or -2.5 V to +2.5 V and is determined by the offset voltage at the OFFSIN pin. 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 –12 V and VDD = +4.75 V to +12 V and requires a stable 2.5 V reference on REFIN.
