NOTES :
1. Measured at the digital output pins (DO0 to DO9). When the input voltage is 1.0 Vp-p and ADC output is the full scale, the
absolute gain is defined as a 0 dB. The relative gain is the relative value from the absolute gain. The gain monotonicity is
guaranteed except least significant bit.
2. Measured at the digital output pins (DO0 to DO9).

NOTES :
1. Non missing code is guaranteed.
2. Black calibration period (tBKCAL) is specified when the CCAL is from 16 to 127 LSB.
Although black level codes of 1 to 15 could be set, tBKCAL is not guaranteed for these codes.
