TPA2018D1 - Texas Instruments

TPA2018D1 3-W Mono Class-D Audio Amplifier

The TPA2018D1 is a mono, filter-free Class-D audio power amplifier with volume control, dynamic range compression (DRC) and automatic gain control (AGC). It is available in a 1.63 mm x 1.63 mm WCSP package. The DRC/AGC function in the TPA2018D1 is programmable via a digital I2C interface. The DRC/AGC function can be configured to automatically prevent distor.
