Positive Gain Error
This is the deviation of the last code transition (011...110 to
011...111) from the ideal V
the zero code error has been adjusted out.
Negative Gain Error
This is the deviation of the first code transition (100...000 to
100...001) from the ideal VIN+ − VIN– (i.e., –VREF + 1 LSB),
after the zero code error has been adjusted out.
Track-and-Hold Acquisition Time
The track-and-hold acquisition time is the minimum time
required for the track-and-hold amplifier to remain in track
mode for its output to reach and settle to within 0.5 LSB of the
applied input signal.

Power Supply Rejection Ratio (PSRR)
The power supply rejection ratio is the ratio of the power in
the ADC output at full-scale frequency, f, to the power of a
100 mV p-p sine wave applied to the ADC V
frequency f
1 MHz.
Pf is the power at frequency f in the ADC output; Pfs is the
power at frequency f
S
. The frequency of this input varies from 1 kHz to
PSRR (dB) = 10log(Pf/Pf
