3 Audio amplifier stage with AZAD2102 (U163, U164)
3.1 General description
This chassis uses two 2.5 W Class D Mono Audio Amplifers for from 16" to 24"
TVs.
AZAD2102B
is a 2.9 Watts (max. can offer 3.0 Watts @ Load
=
3 Ω,THD = 10%,
AVdd = DVdd = 5.5 Volt) with high efficiency filter-free class-D audio power amplifier
in a 1613 mm x 1613 mm wafer chip scale package (WCSP). AZAD2102B uses
Current- switch technology to achieve high performance class-d amplifier that
features 0.03% THD, 85% efficiency, –70 dB PSRR, to improve RF-rectification immunity.
AZAD2102B provide a Vibration-Spectrum modulation clock for PWM Output. This
vibration frequency is around 10 kHz shift (+/- 5 kHz of Fpwm).
The advantage of the small size package (WCSP) makes AZAD2102B very suitable for
mobile phone and PDA device application. And the Class-D amplifier structure let
AZAD2102B to have highly efficiency power consumption than Class-AB amplifier.
AZAD2102B can shrink the application board, reduce system cost, and external
components.
ESD level protection I/O embedded in AZAD2102B. For general applications, there is
no need to add extra ESD protection devices (like Varistors) in application systems for
AZAD2102B’s I/O.
