The SNAUD01 is a low-power 24-bit stereo audio codec with ADCs, DACs, and build-in headphone driver, audio amplifier, fractional PLL and LDOs.
In microphone recording application, SNAUD01 integrates preamps for stereo differential microphone by reducing external component requirements. With larger boost gain and 24-bit precision ADCs, SNAUD01 is suitable for long distance audio recording. In audio playback application, Mono class-AB audio amplifier is used to drive 8Ω speaker with a 5V supply.
For power management, there are two LDOs supply 3.3V and 1.8V power, which can provide certain current for backend main chip.
SNAUD01 is specified for operation from -20°C to +85°C.
