The SSM2602 Rev. 0 is a low-power audio codec with stereo, 24-bit analog-to-digital and digital-to-analog converters, a highly efficient headphone amplifier, and low power consumption.
The SSM2602 is a low‑power, high‑quality stereo audio codec designed for portable digital audio applications such as mobile phones, MP3 players, and educational toys. It offers 24‑bit ADC and DAC channels, programmable gain amplifiers, and can operate as either master or slave with a wide range of audio sampling rates.
Key specifications include analog supply voltages from 1.8 V to 3.6 V, digital core supplies from 1.5 V to 3.6 V, power consumption as low as 7 mW for stereo playback, and an SNR of up to 100 dB (A‑weighted) for the DAC. The device is supplied in a 28‑lead 5 mm × 5 mm LFCSP package and operates over an industrial temperature range of –40 °C to +85 °C.
