TLV320ADC5140 - Texas Instruments

TLV320ADC5140 Quad-Channel Audio ADC

The TLV320ADC5140 is a Burr-Brown™ highperformance, 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. The device supports line and microphone inputs, and allows for both single-ended and differential input configurations..
