Negative Gain Error

This is the deviation of the first code transition (100...000 to

100...001) from the ideal VIN+ – VIN– (that is, –VREF + 1 LSB),

after the zero code error has been adjusted out.

Track-and-Hold Acquisition Time

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 ratio of the power in the ADC output at full-scale fre-

quency, f, to the power of a 100 mV p-p sine wave applied to the

ADC VDD supply of frequency fS. The frequency of this input

varies from 1 kHz to 1 MHz.

PSRR(dB) = 10log(Pf/PfS)

Pf is the power at frequency f in the ADC output; Pfs is the

power at frequency fS in the ADC output.
