The WEA10IDA45 is a 10-bit current DAC. It accepts a current input of 4 uA and is capable of sinking and sourcing current up to 4 mA The DAC output has 1023 sink and 1023 source settings that is programmed using a parallel 10-bit digital bus. The current DAC output can be switched to high impedance state. The iDAC operates from a power supply ranging from 1.8 V to 3.0 V. The WEA10IDA45 absolute accuracy is maintained in a range of +/-300 mV from the supply rails.
