Componente care suportă interfața I2S
- CS5343/4 – The CS5343/4 is a complete analog-to-digital converter for digital audio systems. It performs sampling, analog-to-digital conversion, and anti-alias filtering, generating 24-bit values for both left and right inputs in serial form at sample rates up to 108 kHz per channel.
- CS4344/5/8 – The CS4344 family members (CS4344, CS4345, and CS4348) are complete, stereo digital-to-analog output systems including interpolation, multibit D/A conversion and output analog filtering in a 10-pin package. The CS4344 family supports major audio data interface formats. Individual devices differ only in the supported interface format.
- MAX9880A – Low-Power, High-Performance, Dual I²S, Stereo Audio Codec; The MAX9880A is a high-performance, stereo audio codec designed for portable consumer applications such as smartphones and tablets. Operating from a single 1.8V supply to ensure low-power consumption, the MAX9880A offers a variety of input and output configurations for design flexibility. The MAX9880A can be combined with an audio subsystem, such as the MAX9877 or MAX9879, for a complete audio solution for portable applications.
