3)
1. All voltages values are measured with respect to the ground pin.
2.
Pd has been calculated with Tamb = 25°C, Tjunction = 150°C.
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 exces-
sive heating and the destruction of the device.

Functional Description
Rin
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))
Cin
Input coupling capacitor which blocks the DC voltage at the amplifier input terminal
Rfeed
Feed back resistor which sets the closed loop gain in conjunction with Rin
Cs
Supply Bypass capacitor which provides power supply filtering
Cb
Bypass capacitor which provides half supply filtering
Cout
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))
Rpol
These 2 resistors form a voltage divider which provide a DC biasing voltage (Vcc/2) for the 2 amplifiers.
Av
Closed loop gain = -Rfeed / Rin
