Track/Hold Acquisition Time
The time required for the output of the track/hold amplifier to
reach its final value, within ±1/2 LSB, after the point at which
the track/hold returns to track mode. This happens approxi-
mately 120 ns after the falling edge of CONVST .
It also applies to situations where a change in the selected input
channel takes place or where there is a step input change on the
input voltage applied to the selected V
IN
input of the AD7829-1.

It means that the user must wait for the duration of the
track/hold acquisition time after a channel change/step input
change to V
the part operates to specification.
PSR (Power Supply Rejection)
Variations in power supply affect the full-scale transition
but not the converter’s linearity. Power supply rejection is the
maximum change in the full-scale transition point due to a
change in power supply voltage from the nominal value.
