Maximum Ratings*

V

All inputs and outputs w.r.t. V

Storage temperature ..........................-65°C to +150°C

Ambient temp. with power applied .....-65°C to +125°C

ESD protection on all pins (HBM)........................ > 4kV

*Notice: Stresses above those listed under “Maximum ratings”

may cause permanent damage to the device. This is a stress

rating only and functional operation of the device at those or

any other conditions above those indicated in the operational

listings of this specification is not implied. Exposure to maxi-

mum rating conditions for extended periods may affect device

reliability.

Note 1: This parameter is guaranteed by characterization and not 100% tested.

2: See graph that relates linearity performance to V

3: Because the sample cap will eventually lose charge, clock rates below 10 kHz can affect linearity perfor-

mance, especially at elevated temperatures.
