Description
AI
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 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. The TPA2018D1 is capable of driving 3 W at 5 V into 4load or 880 mW at 3.6 V into 8load. The device features hardware and software shutdown controls and also provides thermal and short-circuit protection.
In addition to these features, a fast start-up time and small package size make the TPA2018D1 an ideal choice for cellular handsets, PDAs and other portable applications.
