Electrical Characteristics: VS = 3.3 V (continued)

at TA = 25°C, VS = 3.3 V, GND = 0 V, –4 V ≤ VCM ≤ 27 V, RL = ∞, OFFSET (pin 7) is grounded, and 10 nF between VS and

GND (unless otherwise noted)

MAX(1)

UNIT

(6)

AC common-mode signal is a 5-VPP sine-wave (0 V to 5 V) at the given frequency.

(7)

Positive current corresponds to current flowing into the device.

(8)

For this test input is driven from A1 stage.

(9)

For VOL, RL is connected to VS and for VOH, RL is connected to GND.

(10) Short-Circuit test is a momentary test. Continuous short circuit operation at elevated ambient temperature can result in exceeding the

maximum allowed junction temperature of 150°C.
