com CRD4525 2 x 15 W CS4525 Digital Amplifier Reference Design Features  Output Filters Optimized for 8 Ω Loads  Delivers 15 W/Ch into 8 Ω at 10 % THD+N  Single-Ended 2 VRMS Stereo Analog Inputs  Optical and Coaxial S/PDIF Inputs  Flexible I/O Headers Provided Description The CRD4525 demonstrates the CS4525 digital PWM controller with integrated power stages.
This reference design implements a two-channel amplifier which delivers 15 W per full-bridge channel into 8 Ω loads using a single +18 V supply.
The CRD4525 is powered by an included 80 W switching mode power supply.
Standard RCA phono jacks are provided to easily interface analog input signals with the evaluation board.
Optical and coaxial inputs are provided to interface with S/PDIF digital audio input signals.
The PWM audio power outputs are routed through an inductor/capacitor 2nd order low-pass filter (LPF) to remove high frequency components from the output signal, effectively converting it from digita...
