TPA6102A2 具有固定增益 (14dB) 的超低电压、立体声耳机音频放大器

The TPA6102A2 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- loads. Amplifier gain is internally set to 14 dB (inverting) to save board space by eliminating six external resistors.

The TPA6102A2 is optimized for battery applications because of its low supply current, shutdown current, and THD+N. To obtain the low supply voltage range, the TPA6102A2 biases BYPASS to VDD/4.

When driving a 16- 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- loads, the THD+N is reduced to less than 0.06% at 1 kHz, and is less than 0
