Dolphin Integration announce the launch of sCODp-MT1-VD.02, a voice-oriented converter supporting both analog and digital microphones. It offers high dynamic range over gain range on ADC of 105dB and motor and wind noise filters to reduce the environment disturbance and enhance the voice recognition quality.

Additionally, sCODp-MT1-VD.02 provides a voice detection feature to automatically wake-up the system by voice, microphone inputs with independent programmable gain amplifiers and automatic gain control to prevent saturation of audio signal. The small area and the low EMI emission of sCODp-MT1-VD.02 contribute to position it as a leading cost-effective converter for fabless companies which are active in the growing market of white electronic devices (smart Air conditioner, smart Fridge…) and brown appliance devices (Smart TV, Smart Radio…).

The sCODp-MT1-VD.02 includes unique features, such as spread spectrum and PLL-less functioning, to protect against any performance drop due to noise propagation issues. This product is delivered with its “noise tolerance template” and with advanced views (behavioural models) enabling noise propagation checks by the user.

At 130nm, but easily retargetable from 180-40nm at both TSMC and SMIC, this IP is available now.
