It is also possible to freeze the offset correction using the serial interface (
<OFFSET LOOP FREEZE>). Once
frozen, the offset estimation becomes inactive and the last estimated value is used for correction every clock
cycle. Note that the offset correction is disabled by default after reset.
Figure 101 shows the time response of the offset correction algorithm, after it is enabled.

Gain Correction
ADS62P4X has ability to make fine corrections to the ADC channel gain. The corrections can be done in steps of
0.05 dB, up to a maximum of 0.5 dB, using the register bits ( GAIN CORRECTION). Only positive corrections are
supported and the same correction applies to both the channels.
