The TLV320ADC5140 is a Burr-Brown™ high-performance, 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. The device integrates programable channel gain, digital volume control, a programmable microphone bias voltage, a phase-locked loop (PLL), a programmable high-pass filter (HPF), biquad filters, low-latency filter modes, and allows for sample rates up to 768 kHz. The device supports time-division multiplexing (TDM), I2S, or left-justified (LJ) audio formats, and can be controlled with either the I2C or SPI interface. These integrated high-performance features, along with the ability to be powered from a single-supply of 3.3 V or 1.8 V, make the device an excellent choice for space-constrained audio systems in far-field microphone recording applications.

The TLV320ADC5140 is specified from –40°C to +125°C, and is offered in a 24-pin WQFN package.
