The output of the AD5422 with the voltage and current output pins tied together as in figure 77 of the datasheet. The circuit also designed with the external boost transistor. The AD5422 outputs 19.7mA .3mA shy of the 20mA specification. when the DAC is set to output the lowest value the measurement is 3.9mA. Any suggestions on getting a bit closer to the specifications?
