Note 1:
FB accuracy is 100% tested at FB = 3.5V (code 10000) with V
CC
= V
DD
= 4.5V to 5.5V and CSH - CSL = 0mV to 80mV. The
other DAC codes are tested at the major transition points with V
CC
= V
DD
= 5V and CSH - CSL = 0. FB accuracy at other
DAC codes over line and load is guaranteed by design.
Note 2:
FB set voltage is 100% tested with V
CC
= V
DD
= 4.5V to 5.5V and CSH - CSL = 0mV to 80mV.
Note 3:
AC load regulation sets the AC loop gain, to make tradeoffs between output filter capacitor size and transient response,
and has only a slight effect on DC accuracy or DC load-regulation error.
Note 4:
Specifications from 0°C to -40°C are not production tested.
