CHARACTERISTICS

Absolute Maximum Ratings*

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

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

Soldering temperature of leads (10 seconds) ............. +300°C

ESD protection on all pins.............................................> 4 kV

*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

operation listings of this specification is not implied. Exposure

to maximum rating conditions for extended periods may affect

device reliability.

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

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

performance, particularly at elevated temperatures. See Section 6.2, “Maintaining Minimum Clock Speed”,

for more information.
