Voice A/D

 

Phoenics Electronics carries 1, 2, and 4 channel microphone arrays from Conexant. The CX20811 is a 4 Channel High Performance Microphone Array ADC with Programmable Pre-amplifier and Class D PWM Out. The CX2081x is suitable for voice recognition, control, and conferencing applications and other applications requiring voice control.  

The device supports a microphone array with up to four synchronized ADCs and programmable pre-amplifiers. Each preamplifier has a dedicated micbias supply that eliminates crosstalk. The entire input path guarantees 106dB dynamic range, which allows the voice system to use the full performance of a high SNR microphone using low microphone boost to prevent microphone saturation. This path is critical for far field applications and also ideal for compact speaker-phone designs where the microphone and speakers are in close proximity.
