description

The TPA6101A2 is a stereo audio power amplifier packaged in either an 8-pin SOIC package or an 8-pin MOSP

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

is internally set to 2 dB (inverting) to save board space by eliminating six external resistors.

The TPA6101A2 is optimized for battery applications because of its low-supply current, shutdown current, and

THD+N. To obtain the low-supply voltage range, the TPA6101A2 biases BYPASS to V /4.

When driving a 16-Ω load with 40-mW output power from 3.3 V, THD+N is 0.08% at 1 kHz, and less than 0.2%

across the audio band of 20 Hz to 20 kHz. For 30 mW into 32-Ω loads, the THD+N is reduced to less than 0.06%

at 1 kHz, and is less than 0.3% across the audio band of 20 Hz to 20 kHz.
