Overview
The SSM2604CPZ-REEL7, produced by Analog Devices Inc., is a low power, high-quality stereo audio codec designed for portable digital audio applications. This component is particularly suited for devices such as mobile phones, MP3 players, portable gaming devices, and educational toys. It features a pair of 24-bit analog-to-digital converter (ADC) channels and a pair of 24-bit digital-to-analog converter (DAC) channels, along with a set of stereo programmable gain amplifier (PGA) line inputs. The SSM2604 can operate as either a master or a slave and supports various master clock frequencies, making it versatile for different audio sampling rates.
