YDA137 Datasheet | YAMAHA CORPORATION

D- 2 STEREO 5W DIGITAL AUDIO POWER AMPLIFIER - Overview YDA137 (D-2) is a high efficient digital audio power amplifier IC that operates on a single 5V power supply. With YDA137 in BTL connection, an audio power amplifier with a maximum output of 5W (RL=2Ω)×2ch can be configured with one chip. YDA137 converts an input analog data into a digital pulse by the digital modulation circuit in the IC and outputs a high current digital pulse from the output buffer circuit. This digital pulse signal is converted into an audio signal by an external low-pass filter and is output to the speaker. Low-distortion rate characteristics and high S/N ratio are realized as a digital amplifier among same...
