PRODUCTION DATA
The calibration (CAL) pin may be used to execute an on-command calibration. The effect of calibration is to maximize the dynamic performance. To initiate an on-command calibration through the CAL pin, bring the CAL pin high for a minimum of tCAL_H input clock cycles after it has been low for a minimum of tCAL_L input clock cycles (see Converter Electrical Characteristics: AC Electrical Characteristics clock cycle specification). TI recommends holding the CAL pin high during normal usage of the ADC12D1620 device to reduce the chance that an SEU causes a calibration cycle. In ECM, this pin remains active and is logically OR'd with the CAL bit.
To use this feature in ECM, use the CAL bit in the Configuration Register (Addr: 0h; Bit: 15). See Calibration Feature for more information.
