3.3V Electrical Characteristics (continued)

The following specifications apply for single supply with VS = 3.3V, RL = 100Ω terminated to 1.65V, gain = 10V/V, VO = 1VPP,

VCM = VS/2, COMP Pin = HI (WSON-8 package), unless otherwise noted. Boldface limits apply at the temperature extremes.

(3)

The maximum continuous output current (IOUT) is determined by device power dissipation limitations. Continuous short circuit operation

at elevated ambient temperature can result in exceeding the maximum allowed junction temperature of 150°C

(4)

Drift determined by dividing the change in parameter at temperature extremes by the total temperature change.

(5)

Negative input current implies current flowing out of the device.
