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. VOUT for this DAC is then updated to reflect the new contents of the DAC register. Channel selection is accomplished via the parallel address inputs A0A4 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 VSS + 2 V to VDD 2 V because of the headroom of the output amplifier.
