ELECTRICAL CHARACTERISTICS: V_S = ±6V (continued)
At T_A = +25°C, G_DIFF = +5V/V with R_L = 100Ω differential load, R_ADJ = 0Ω, active impedance circuit configuration, and full bias,
unless otherwise noted. Each port is independently tested.

FUNCTION
DESCRIPTION
Full bias mode (100%) Amplifiers on with lowest distortion possible (default state)
Mid bias mode (75%) Amplifiers on with power savings and a reduction in distortion performance
Low bias mode (50%) Amplifiers on with enhanced power savings and a reduction of overall performance
Shutdown mode Amplifiers off and output has high impedance
