All characteristics are measured with zero common-mode input voltage unless otherwise noted. Full range is –55

°C to 125°C.

IMPORTANT: See Parameter Measurement Information.

(2)

The offset voltage limits given are the maximum values required to drive the output above 4 V or below 400 mV with a 10-k

Ω resistor

between the output and VDD. They can be verified by applying the limit value to the input and checking for the appropriate output state.
