DESCRIPTION
The TS482 is a dual audio power amplifier able to drive a 16 or 32Ω stereo headset down to low volt­ages.
It’s delivering up to 100mW per channel (into 16Ω loads) of continuous average power with 0.1% THD+N from a 5V power supply.
The unity gain stable TS482 can be configured by external gain-setting resistors.

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 co ntinu ous power dis sipati on. Exp osure of the I C to a short ci rcuit on one or two amp lifi ers simul taneousl y can c ause exces­sive heating and the destruction of the device.

Components Functional Description
Rin
Cin
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 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
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
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))
