Output Short-Circuit Duration

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.

Components

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
