NAU8810 Differential/Mono Audio Codec with 2-wire Interface Control Interface emPowerAudio™ 1. GENERAL DESCRIPTION The NAU8810 a cost effective low power wideband Monophonic audio CODEC. It is suitable for a wide range of audio applications, including voice telephony. Supported functions include a...
To enable the codec, you must add the codec under the device tree node of the device that is used to access the codec. Most codecs use either I2C or SPI for access. In the example below, the codec uses I2C for its control interface, and so is added to the appropriate I2C node...
STA529 FFX™ audio codec with analog and digital inputs and 2 x 1.2 W (or 2 x 100 mW HP) class-D amplifier Datasheet − production data Features ■ Up to 96 dB dynamic range ■ Sample rates from 8 kHz to 192 kHz ■ FFX™ class-D driver ■ 1.55 V to 1.95 V digital power...
The STM32 MCU configures the audio codec via the I2C and transmits audio samples via the I2S. The codec is connected to the analog speaker. For audio recording, the STM32 board is recognized by the PC as a USB microphone. MEMS microphones capture the sound as PDM samples...
