Automotive, stereo, 123-dB SNR, 768-kHz, low-power software-controlled audio ADC | RTE | 20 | -40 to 125

The PCM6120-Q1 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.

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 PCM6120-Q1 is

specified from –40°C to +125°C, and is offered in a 20-pin WQFN package.
