Note 1: The offset voltage distribution is centered around 0V. The typical offset number shown is equal to the stan-

dard deviation of the voltage offset distribution.

2: Specification for packaged product only. Exceeding the maximum differential input voltage will damage the

input stage and degrade performance (in particular, input bias will likely increase).
