Notes:
1. One input grounded; dc to 20kHz, Full Scale input on the other channel.
Guaranteed by characterization.
2. Applies only in the track mode. When converting or calibrating, input capacitance will typically
be 10 pF.
3. All outputs unloaded. All inputs CMOS levels.
4. Power dissipation in sleep mode applies with no master clock applied (CLKIN high or low).
5. With 300mV p-p, 1kHz ripple applied to each supply separately. A plot of typical power supply
rejection appears in the Analog Circuit Connections section.
* Refer to Parameter Definitions at the end of this data sheet.
Specifications are subject to change without notice.
