General Description

YDA164(D-510D) is a high-performance digital audio amplifier IC that delivers up to 20W×2ch, which has a digital audio interface, and is capable of operating at a supply voltage ranging from 8V to 18V.

YDA164, having “Pure Pulse Direct Speaker Drive Circuit” that drives a speaker directly by reducing distortion and noise due to PWM pulse outputs, realizes the highest degree of low-level distortion and noise characteristics in all of mobile digital amplifiers.

In addition, because of a feedback-type digital amplifier, this amplifier is insusceptible to supply voltage fluctuation, allowing for the use of a non-regulated power supply and allowing a simple amplifier system with less external components to be configured.
