of operating functions

YDA145 has digital amplifiers with analog input, PWM pulse output, and maximum output of 2.1W(RL=4Ω)×1ch.

Distortion of PWM pulse output signal and noise of the signal is reduced by adopting “Pure Pulse Direct Speaker Drive Circuit”.

m output 2.1 W×1ch (VDD=5.0V, RL=4Ω, THD+N=10%) 0.75 W×1ch (VDD=3.6V, RL=8Ω, THD+N=10%) Distortion Rate (THD+N) 0.03 % (VDD=3.6V, RL=8Ω, Po=0.4W, 1kHz) Residual Noise 45µVrms (VDD=3.6V, Av=18dB) www. DataSheet4U. com Efficiency 84 % (VDD=3.6V, RL=8Ω, Po=600mW) 78 % (VDD=3.6V, RL=8Ω, Po=100mW) S/N Ratio 94dB (VDD=3.6V, Av=18dB) Over-current Protection function Thermal Protection function Low voltage Malfunction Prevention function Pop noise reduction function Power-down control function Power-down.
