3 Description

The TPA2026D2 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.

The DRC and AGC function in the TPA2026D2 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 0 dB to +30 dB in 1-dB steps.

The TPA2026D2 is capable of driving 3.2 W/Ch at 5

V into an 4-

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

load. The device features independent software

shutdown controls for each channel and also provides

thermal and short-circuit protection. The TPA2026D2

has faster AGC gain ramp during start-up than

TPA2016D2.

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

small package size make the TPA2026D2 an ideal

choice

for

cellular

handsets,

PDAs,

and

other

portable applications.
