TPA2016D2RTJR

TEXAS INSTRUMENTS  TPA2016D2RTJR  音频功率放大器, QFN

The is a stereo filter-free Class D Audio Power Amplifier with volume control, dynamic range compression DRC and automatic gain control AGC. The DRC/AGC function in the TPA2016D2 is programmable via a digital I²C interface. The DRC/AGC function can be configured to automatically prevent distortion of the audio signal and enhance quiet passages that are normally not heard. The DRC/AGC can also be configured to protect the speaker from damage at high power levels and compress the dynamic range of music to fit within the dynamic range of the speaker. The gain can be selected from -28 to +30dB in 1dB steps. The TPA2016D2 is capable of driving 1.7W/Ch at 5V or 750mW/Ch at 36V into 8R load or 2.8W/Ch at 5V or 1.5W/Ch at 3.6V into 4R load. The device features independent software shutdown controls for each channel and also provides thermal and short-circuit protection.
