PRODUCTION DATA
If PDI and PDQ are simultaneously asserted during a calibration cycle, the ADC12D1620 device immediately powers down. The calibration cycle continues when either or both channels are powered back up, but the calibration is compromised due to the incomplete settling of bias currents directly after power up. Therefore, a new calibration must be executed upon powering the ADC12D1620 back up. In general, the ADC12D1620 must be re-calibrated when either or both channels are powered back up, or after one channel is powered down. For best results, this must be done after the device has stabilized to its operating temperature.
