Additional Details:

The SSM2605GY operates from a single 2.5V to 3.6V power supply. The ADC and DAC both support sample rates from 8 kHz to 96 kHz. The integrated headphone amplifier can drive headphones with impedances ranging from 16 ohms to 32 ohms. The device is available in a 28-pin TSSOP package. It also supports various audio formats, including PCM, I2S, and TDM. The codec's performance is characterized by a THD+N (Total Harmonic Distortion + Noise) of typically -90dB. The device also includes advanced power management features, such as automatic power-down and clock gating, to further reduce power consumption. The I2C interface provides access to a wide range of control registers, allowing for precise control over the codec's various parameters. The integrated microphone bias supply provides a stable and regulated voltage for powering external microphones.
