Overview
The PCM3060PWR, produced by Texas Instruments, is a low-cost, high-performance, single-chip 24-bit stereo audio codec. It features single-ended analog inputs and differential analog outputs, making it suitable for a variety of audio-visual applications. This codec supports asynchronous operation for both the ADC and DAC, allowing for independent control of the sampling rate and audio interface. The PCM3060PWR is fabricated using an advanced CMOS process and is available in a compact 28-pin TSSOP package.
