SPECIFICATIONS

TA = 25°C, ±VS = ±5 V except as noted, CAV = 33 μF, CC = 10 μF, f = 1 kHz, sine wave input applied to Pin 2, unless otherwise specified.

Specifications shown in boldface are tested on all production units at final electrical test. Results from these tests are used to calculate

outgoing quality levels.
