Applications that use voice capture or voice command are often subjected to a variety of environmental challenges that can impede their ability to perform properly.  While state-of-the-art speech recognition systems perform reasonably well in close-talking microphone conditions, performance degrades in noisy environments and in conditions where the microphone is far from the user.  Learn about the most common challenges faced by voice capture applications, and see how those challenges can be substantially reduced with high-performance audio ADCs.

The TLV320ADC5140 is a high-performance, TI Burr-Brown™ audio analog-to-digital converter (ADC) that supports simultaneous sampling of up to four analog channels or eight digital channels for the pulse density modulation (PDM) microphone input.  Engineers can now achieve 120-dB dynamic range for clear, high-fidelity audio in smart home applications.
