It features a PDM to PCM conversion for microphone acquisition and either PCM to PWM output or PCM to PDM output depending on the application needs. This generation of stereo Audio CODEC is also provided with a large set of options enabling the user to build an optimised solution.

The sCODi-MT1-DS.01 (with PWM output) and the sCODi-N1-DS.01 (with PDM output) achieve SNR performances as high as 100 dB on the acquisition path (PDM to PCM) and 105 dB on the emission path (PCM to PWM/PDM).

Key features include:

Multi-channel capabilities with embedded synchronisation and audio phase alignment

Support of multi-mode digital microphones

8-bit looped pattern generation to control external amplifiers

Anti pop-up noise control signal

Spread-spectrum feature for safe integration with RF transceivers

Optional delivery with a voice trigger enabling the detection of the presence of voice to wake-up the rest of the SoC

Full logic design, enabling test cost savings with pure logic SCAN test

These new products are delivered with a set of application schematics enabling the user to assemble an optimised solution for the required performance while guaranteeing the lowest BoM cost. Their flexibilities enable supporting a large set of output peripherals, such as:

Sound amplifiers with analogue inputs

Sound amplifiers with digital inputs

Line output (up to 6 Vrms)

16/32/50 Ω headphones

Dolphin Integration;
