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 with V CC = V DD = 5V and CSH - CSL = 0.
Note 2: 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 3: Specifications from 0°C to -40°C are guaranteed by design, not production tested.
