Stresses exceeding Maximum Ratings may damage the device. Maximum Ratings are stress ratings only. Functional operation above the
Recommended Operating Conditions is not implied. Extended exposure to stresses above the Recommended Operating Conditions may affect
device reliability.
DC ELECTRICAL CHARACTERISTICS Standard test conditions, VCC = 15 V, TA = 25°C; Expandor mode (see Test Circuit). Input
signals at unity gain level (0 dB) = 100 mVRMS at 1.0 kHz; V1 = V2; R2 = 3.3 kW; R3 = 17.3 kW, unless otherwise noted.
