Test conditions: VDD = VCC = 5.0 V, MCLK frequency 13.0 MHz, no load on digital pins, analog inputs ac-coupled to ground, no load on analog output
(VOUTP–VOUTN)
IActive: AD28msp02 operational (PWDD and PWDA set to 1 in control register).
2Inactive: AD28msp02 in powerdown state (PWDD and PWDA set to 0 in control register) and MCLK tied to V
DD.
