D-515

STEREO 5W-15W DIGITAL AUDIO POWER AMPLIFIER

■General Description

YDA147 (D-515) is a high-efficiency digital audio power amplifier IC with the maximum output of 15W × 2ch.

YDA147 has a “Pure Pulse Direct Speaker Drive Circuit” that directly drives speakers while reducing distortion of

pulse output signal and reducing noise on the signal, which realizes the highest standard low distortion rate

characteristics and low noise characteristics among digital amplifier ICs in the same class.

In addition, supporting filterless design allows circuit design with fewer external parts to be realized depending on use

conditions.

YDA147 features Power Limit Function, Non-clip Function, and DRC (Dynamic Range Control) Function that were

developed by Yamaha original digital amplifier technology.

YDA147 has overcurrent protection function for speaker output terminals, high temperature protection function, and

lowsupply voltage malfunction prevention function.

■Features

・PSRR

60dB (V_DDP=12V,Vripple=100mV, 1kHz, GAIN[1:0]=L,L, NCDRC[1:0]=L,L)

・Non-clip function/DRC function (switchable)

・Power limit function

・Clock External Synchronization Function

・Master/Slave Synchronization Function using clock outputs

・Over-current Protection Function, High Temperature Protection Function,

Low Voltage Malfunction Prevention Function, and DC Detection Function

・Sleep Function using SLEEPN terminal and Output Mute Function using MUTEN terminal

・Stereo/Monaural Switching Function

・Spread Clock Function

・Pop Noise Reduction Function

・Package

Lead-free 48-pin Plastic SQFP (Exposed stage)

Lead-free 48-pin Plastic LQFP
