General Description
The APA2036/APA2036A is a stereo audio power ampli-
fier in a TQFN4x4-16 or TQFN3x3-16 (APA2036A) package.
To simplify the audio system design in notebook com-
puter applications, the APA2036/APA2036A combines a
stereo bridge-tied mode for speaker drive and a stereo
single-end mode for headphone drive into a single chip,
where both modes are easily switched by the SE/BTL
input control pin signal. When the APA2036/APA2036A is
in the BTL mode with 5V supply voltage, it is capable of
delivering 2.4W/2.0W/1.3W of continuous output power
per channel into 3Ω/4Ω/8Ω load (Speaker) with less than
1% THD+N respectively. When the APA2036/APA2036A
operates in the single-ended mode, it is capable of deliv-
ering 160mW/85mW of continuous output power per chan-
nel into 16Ω/32Ω load (Headphone).
The APA2036/APA2036A also serves low-voltage appli-
cations well.
The APA2036/APA2036A, with 3.3V supply voltage, pro-
vides 900mW (at 1% THD+N) per channel into 4Ω load.
Both of the depop circuitry and the thermal shutdown pro-
tection circuitry are integrated in the APA2036/APA2036A.
The depop function reduces pops and clicks noise dur-
ing power on/off and enable/shutdown processes. The
thermal protection protects the chip from being destroyed
by over-temperature failure. For power sensitive
applications, the APA2036/APA2036A also features a shut-
down function which reduces the supply current only
0.5µA (typical).
