AD5532: 32-Channel 14-Bit Bipolar Voltage-Output DAC

The AD5533 combines a 32 channel voltage translation function with an infinite output hold capability. An analog input voltage on the common input pin, Vin, is sampled and its digital representation transferred to a chosen DAC register. V_OUT for this DAC is then updated to reflect the new contents of the DAC register. Channel selection is accomplished via the parallel address inputs A0-A4 or via the serial input port. 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 V_SS+2V to V_DD-2V because of the headroom of the output amplifier.

The device is operated with AV_CC = +5V±5%, DV_CC= 2.7V to 5.25V, V_SS = –4.75V to –16.5V and V_DD= 8V to 16.5V and requires a stable +3V reference on REF_IN as well as an offset voltage on OFFS_IN. It is available in a 74-lead 12mm x 12mm LFBGA package.

Also see the AD5532. It is similar to the AD5533 as it is specified in the infinite sample and hold mode of operation, but it has an additional 32-channel, voltage-output 14-bit DAC.
