General Description

The APA2605, APA2606, APA2607 is a stereo, high efficiency, filter-free Class-

D audio amplifier available in SOP-18, SSOP-24,

SSOP-24P, and QFN4x4-20A packages.

The APA2605 provides the precise DC volume control,

the gain range is from -80dB (V VOLUME=0V) to +20dB

(VVOLUME=5V) with 64 steps precise control. It’s easy to get

the suitable amplifier’s gain with the 64 steps gain setting.

The filter-free architecture eliminates the output filters

compared to the traditional Class-D audio amplifier, and

reduces the external component counts and the compo-

nents high, it could save the PCB space, system cost,

simplifies the design and the power loss at filter.

APA2605 provides an AGC (Non-Clip) function, and this

function can low down the dynamic range for large input

signal. APA2605 can provide from 20dB to -80dB with 64

steps gain decrease for non-clipping function, and this

function can avoid output signal clipping.

The APA2605 also integrates the de-pop circuitry that re-

duces the pops and click noise during power on/off or

shutdown enable process.

The APA2605 has build-in over-current and thermal pro-

(RoHS Compliant)

Applications

tection that prevent the chip being destroyed by short-

circuit or over-temperature situation.

APA2605 is capable of driving 2.8W at 5V into 4Ω speaker.
