Part Description

The TPA2028D1 device is a mono, filter-free Class-D audio power amplifier with volume control, fast gain ramp SmartGain™, dynamic range compression (DRC), and automatic gain control (AGC). It is available in a 1.63 mm × 1.63 mm wafer chip-scale package (DSBGA). The DRC/AGC function in the TPA2028D1 device is programmable through 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 TPA2028D1 is capable of driving 3 W at 5 V into a 4-Ω load or 880 mW at 3.6 V into an 8-Ω load. The device features hardware and software shutdown controls and also provides thermal and short-circuit protection. The TPA2028D1 has a faster AGC gain ramp during start-up than TPA2018D1. In addition to these features, a fast start-up time and small package size make the TPA2028D1 an ideal choice for cellular handsets, PDAs and other portable applications.
