IG02980 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 10W (RL=8Ω) ×2ch or 20W (RL=4Ω) ×1ch can be configured with one chip and realizes the highest standard low distortion rate and low noise behavior as 10W-class of output digital amplifier.
Important features Digital Amplifier are;
1- Continuous maximum output 10 W×2ch @VDDP=12.0V, RL=8Ω, THD+N=10% 20 W×1ch @VDDP=12.0V, RL=4Ω,
THD+N=10%
2- Efficiency 88 % @VDDP=12.0V, RL=8Ω, Po=10W
3- Distortion Rate (THD+N) 0.02 % @VDDP=12.0V, RL=8Ω, Po=1.0W
4- S/N Ratio 103dB @VDDP=12.0V, RL=8Ω, Po=10W, VOL[1:0]=H,H
5- Channel Separation -70dB @VDDP=12.0V, RL=8Ω,
6- Maximum output 50mW×2ch @VDDP=12.0V, RL=32Ω, THD+N=10%
7- Distortion Rate(THD+N) 0.01 % @VDDP=12.0V, RL=32Ω, Pho=30mW
8- S/N Ratio 95dB @VDDP=12.0V, RL=32Ω, Pho=20mW, VOL[1:0]=H,H
The use of this module is as a “Pure Pulse Direct Speaker Drive Circuit” which directly drives speakers while reducing distortion of pulse output signal and reducing noise on the signal. In addition, using this IC a circuit design with fewer external parts can be made depending on the condition of use because corresponds to filter less. Also it can be used to design a 50mW (RL=32Ω)×2ch Class AB headphone amplifiers.
It provides Over-current protection function for speaker output terminals, IC thermal protection function, POP noise reduction function, and AM interference measures function as well as power-down function and output mute function. Image below shows a Yamaha dual channel amp made using IG02980.

I recently purchased the integrated circuit IG02980 from Utsource and I am very pleased with the qu of the product. The circuit was tested thoroughly and it performed as expected. The delivery was also very prompt and the customer service was excellent. I would highly recommend Utsource for anyone looking for qu integrated circuits.
