ELECTRICAL CHARACTERISTICS: VS = +3.3V

Boldface limits are tested at +25

°C.

At TA = 25°C, G = +2, and RL = 150Ω to VCM = 0.75V, unless otherwise noted (see Figure 2).

(1) Junction temperature = ambient for +25°C specifications.

(2) Junction temperature = ambient at low temperature limits; junction temperature = ambient +5°C at high temperature limit for over temperature.

(3) Test levels: (A) 100% tested at +25°C. Over temperature limits by characterization and simulation. (B) Limits set by characterization and simulation. (C) Typical value only

for information.

(4) Current is considered positive out of node.
