DESCRIPTION

The TPA6100A2D is a stereo audio power amplifier packaged in either an 8-pin SOIC package or an 8-pin

MSOP package capable of delivering 50 mW of continuous RMS power per channel into 16-W loads. Amplifier

gain is externally configured by a means of three resistors per input channel and does not require external

compensation for settings of 1 to 10.

The TPA6100A2D is optimized for battery applications because of its low supply current, shutdown current, and

THD+N. To obtain the low-supply voltage range, the TPA6100A2D biases BYPASS to VDD/4. A resistor with a

resistance equal to RF must be added from the inputs to ground to allow the output to be biased at VDD/2.

When driving a 16-W load with 45-mW output power from 3.3 V, THD+N is 0.04% at 1 kHz, and less than 0.2%

across the audio band of 20 Hz to 20 kHz. For 28 mW into 32-W loads, the THD+N is reduced to less than 0.03%

at 1 kHz, and is less than 0.2% across the audio band of 20 Hz to 20 kHz.
