TPA2028D1 具有快速增益提升 SmartGain(TM) AGC 和 DRC 的 3.0W 单声道 D 类音频放大器

The TPA2028D1 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 × 1,63 mm wafer chip-scale package (WCSP).

The DRC/AGC function in the TPA2028D1 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 dB to +30 dB in 1-dB steps
