1. All voltages values are measured with respect to the ground pin. 2. Pd has been calculated with Tamb = 25C, Tjunction = 150C. 3. Attention must be paid to continuous power dissipation. Exposure of the IC to a short circuit on one or two amplifiers simultaneously can cause excessive heating and the destruction of the device.

Functional Description Inverting input resistor which sets the closed loop gain in conjunction with Rfeed. This resistor also forms a high pass filter with Cin (fc = 1 / (2 x Pi x Rin x Cin)) Input coupling capacitor which blocks the DC voltage at the amplifier input terminal Feed back resistor which sets the closed loop gain in conjunction with Rin Supply Bypass capacitor which provides power supply filtering Bypass capacitor which provides half supply filtering Output coupling capacitor which blocks the DC voltage at the load input terminal This capacitor also forms a high pass filter with RL (fc = 1 / (2 x Pi x RL x Cout)) These 2 resistors form a voltage divider which provide a DC biasing voltage (Vcc/2) for the 2 amplifiers. Closed loop gain = -Rfeed / Rin
