TPA5050 具有 I2C 控制的立体声数字音频延迟处理器

TPA5050 说明

The TPA5050 accepts a single serial audio input, buffers the data for a selectable period of time, and outputs the delayed audio data on a single serial output. One device allows delay of up to 170 ms/ch (fs = 48 kHz) to synchronize the audio stream to the video stream in systems with complex video processing algorithms. If more delay is needed, the devices can be connected in series.
