YDA164 PRELIMINARY
D-510D
DIGITAL INPUT STEREO 15W DIGITAL AUDIO POWER AMPLIFIER
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.
YDA164 has the following functions: power limit function, output disable function, overcurrent protection function for speaker
output pins, internal overtemperature protection function, low-voltage malfunction prevention function, and DC detection
function.

(Note) Absolute Maximum Ratings are values which must not be exceeded to guarantee device reliability and life, and when
using a device in excess of the ratings for even a moment, it may immediately cause damage to the device or may
significantly deteriorate its reliability.
