YDA143 D- 3M STEREO 15W DIGITAL AUDIO POWER AMPLIFIER ■Overview YDA143 (D-3M) is a high efficient digital audio power amplifier IC that operates with a single 12V power supply. An audio power amplifier with a maximum output of 15W (RL=4Ω) 2ch can be configured with one chip. YDA143 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 c.

YDA143 D- 3M STEREO 15W DIGITAL AUDIO POWER AMPLIFIER ■Overview YDA143 (D-3M) is a high efficient digital audio power amplifier IC that operates with a single 12V power supply. An audio power amplifier with a maximum output of 15W (RL=4Ω) 2ch can be configured with one chip. YDA143 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 15W-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. YDA143 has 50mW (RL=32Ω) 2ch Class AB headphone amplifiers. YDA143 provides Over-current protection function for speaker output terminals, IC thermal protection function, and POP noise reduction function as well as power-down function and output mute function. ■Features Digital Amplifier ・Continuous maximum output 15 W×2ch (VDDP=12.0V, RL=4Ω, THD+N=10% ・Efficiency 87 % (VDDP=12.0V, RL=4Ω, Po=15W) ・Distortion Rate (THD+N) 0.04 % (VDDP=12.0V, RL=4Ω, Po=1.5W) ・ S/N Ratio www.DataSheet4U.com 103dB (VDDP=12.0V, RL=4Ω, Po=15W, GAIN[1:0]=H,H) ・Channel Separation -65dB (VDDP=12.0V, RL=4Ω, GAIN[1:0]=H,H) Class AB Headphone Amplifier ・Maximum output 50mW×2ch (VDDP=12.0V, RL=32Ω, THD+N=10 % ・Distortion Rate(THD+N) 0.01 % (VDDP=12.0V, RL=32Ω, Pho=25mW) ・S/N Ratio 95dB (VDDP=12.0V, RL=32Ω, Pho=50mW, GAIN[1:0]=H,H) Others ・Operating power supply range 9.0V to 13.5V ・Multi-channel synchronizing operation by Master/Slave switching function ・Carrier frequency switching function 524kHz/466kHz ・Sleep function with SLEEPN terminal ・Output muting function with MUTEN terminal ・Over-current protection function ・Thermal protection function ・Clock stop protection function ・Pop noise reduction function ・Analog input/BTL (Bridge-Tied Load) output ・Lead-free 52-pin SSOP (YDA143-EZ) YDA143 CATALOG CATALOG No.:LSI-4DA143A20 2006.6 YDA143 ■Terminal configuration www.DataSheet4U.com <52-pin SSOP Top View> 2 YDA143 ■Terminal function No. 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 Name HPOR AVSS VSSBGR VREFR INR MUTEN NC VSS VSS PVDDPR PVDDPR OUTPR VSS PVSSR OUTMR PVDDMR PVDDMR VSS VSS NC PROTN SLEEPN DVSS CKIO XO XI I/O O GND GND O I I GND GND Power Power O GND GND O Power Power GND GND O/D I GND I/O O I Function Voltage tolerance LV LV LV LV HV HV HV HV HV HV HV HV LV LV LV LV LV LV LV LV LV HV HV HV HV HV HV LV LV LV HV LV LV R-ch Headphone Output terminal 5V Analog Ground terminal Ground terminal for Reference Voltage Supply R-ch Reference Voltage terminal (with external capacitor) R-ch Analog Signal Input terminal Mute Control terminal No Connection Ground terminal (This terminal is connected to die-pad of IC) Ground terminal (This terminal is connected to die-pad of IC) R-ch 12V-line VDD terminal R-ch 12V-line VDD terminal R-ch Pos.
