17MB60 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.
