YDA139
D- 4
STEREO 2.5W DIGITAL AUDIO POWER AMPLIFIER
Overview
YDA139 (D-4) is a digital audio power amplifier IC with maximum output of 2.5W (RL=4 )×2ch.
YDA139 has a “Pure Pulse Direct Speaker Drive Circuit” which directly drives speakers while reducing distortion of
pulse output signal and reducing noise on the signal, and realizes the highest standard low distortion rate characteristics
and low noise characteristics as the same class of output digital amplifier IC.
In addition, circuit design with fewer external parts can be made depend on the condition of use because corresponds to
filter less.
YDA139 has the power-down function which can minimize the power consumption in the standby state.
In addition, high speed recovery function provided realizes recovery time within 1ms from the power-down state.
Moreover, Over-current Protection function for speaker output terminals, IC Thermal Protection function, and POP
Noise Reduction function are provided.
YDA139 supports both digital signal input and analog signal input.
