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.
