YDA164

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. „ Features ・Supply Voltage Range ・Input VDDP 8V to 18V VDD 3.0V to 3.6V Digital Audio Interface (Stereo) Sampling Frequency: 32kHz, 44.1kHz, 48kHz Left-justified, MSB first, 1-bit delay, Digital Audio Data 24-bits ・Max.
