3 Description

The TPA2016D2 device is a stereo, filter-free Class-D

audio power amplifier with volume control, dynamic

range compression (DRC), and automatic gain

control (AGC). It is available in a 2.2 mm × 2.2 mm

DSBGA package and 20-pin QFN package.

The DRC and AGC function in the TPA2016D2 is

programmable through a digital I2C interface. The

DRC and AGC function can be configured to

automatically prevent distortion of the audio signal

and enhance quiet passages that are normally not

heard. The DRC and 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 TPA2016D2 is capable of driving 1.7 W/Ch at 5

V or 750 mW/Ch at 3.6 V into 8-Ω load or 2.8 W/Ch

at 5 V or 1.5 W/Ch at 3.6 V into 4-Ω load. The device

features independent software shutdown controls for

each channel and also provides thermal and shortcircuit

protection.

In addition to these features, a fast start-up time and

small package size make the TPA2016D2 an ideal

choice for cellular handsets, PDAs, and other

portable applications.
