The TLV320ADC3120 is a Burr-Brown™ high-performance, audio analog-to-digital converter (ADC) that supports simultaneous sampling of up to two analog channels or four 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 programmable 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, and allows for sample rates up to 192 kHz. The device supports time-division multiplexing (TDM), I2S, or left-justified (LJ) audio formats, and can be controlled with the I2C 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 TLV320ADC3120 is specified from –40°C to +125°C, and is offered in a 20-pin WQFN package.
