DVDD = 3 V, VDDCP = 2.7 V

1 Guaranteed by design. These specifications are not production tested but are supported by characterization data at the initial product release.

2 For gains less than 1/2, a smaller output swing is used.

3 Only G = 1 V/V is production tested.

4 IWB means wire break current.
