2. AUDIO AMPLIFIER STAGE WITH AZAD2102(U163, U164)
2.1. General Description
17MB62 uses two 2,5W Class D Mono Audio Amplifers for from 16” to 24” TVs.
AZAD2102B is a 2.9 Watts (max. can offer 3.0 Watts @ Load = 3Ω,THD=10%,
AVdd=DVdd=5.5Volt)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 10KHZ shift (+/- 5KHZ 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, doesn’t
need to add extra ESD protection device (like Varistors) in application system for
AZAD2102B’s I/O.
