2.65W CLASS-D AUDIO POWER AMPLIFIER
DESCRIPTION
FEATURES
Dedicated RNS(RF-TDD Noise Suppression)
technology
The EEE technology is a super reduction
capability in full frequency span EMI
suppression.
Excellent in the “Pop-Click” noise suppression.
High PSRR: -70 dB (217Hz).
Support 1.8V control logic.
The A2323 is TDD suppression, super low EMI,
single channel, class-D audio power amplifier.
The A2323 designed with the dedicated EEE
(Enhanced Emission Elimination) technology,
reducing great EMI jamming in full frequency span
range, relative to 60cm audio cable, with more than
20dB level capability in FCC standard.
0.1% THD+N (0.4W output power, 4.2V power).
1.15W output power(10% THD ,4.2V power,8Ω
load).
The A2323 internal professional timing control circuit,
fully Suppressed the “Pop-Click” sound, can
effectively erase the transient noise during power up,
power down, power weak and power off in system
operation.
High efficiency in 90%.
Low quiescent current (2.6mA).
Low shut down current ( <0.1uA).
Over current protection, hyper thermal
protection.
ESD discharged protection : ±8kV (HBM).
Latch-up : ± 450 mA.
The A2323 internal over current protection function
and thermal protection function, can effectively
protected chip operation form abnormal damage
condition.
Available in FC-9 Package
