  • 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.
  • WM8960 – The WM8960 is a low power, high quality stereo CODEC designed for portable digital audio applications. Stereo class D speaker drivers provide 1W per channel into 8Ω loads with a 5V supply. Advanced on-chip digital signal processing performs automatic level control for the microphone or line input. Stereo 24-bit sigma-delta ADCs and DACs are used with low power over-sampling digital interpolation and decimation filters and a flexible digital audio interface. The master clock can be input directly or generated internally by an onboard PLL, supporting most commonly-used clocking schemes.
  • WM8962B – Înlocuitorul lui WM8960
  • Cirrus Logic Discontinued Products
  • 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.
