ELECTRICAL CHARACTERISTICS: VS = ±6V (continued)

At TA = +25°C, GDIFF = +5V/V with RL = 100Ω differential load, RADJ = 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
