The Texas Instruments PCM6120-Q1 is a Burr-Brown high-performance, audio ADC that supports simultaneous sampling of up to two analog channels or four digital channels for the PDM microphone input.
The device supports line and microphone inputs, and provides for single-ended and differential input configurations. The device combines programmable channel gain, a programmable microphone bias voltage, digital volume control, a PLL, a programmable high-pass filter, biquad filters, low-latency filter modes, and provides for sample rates up to 768kHz.
The device supports time-division multiplexing, I2S, or left-justified audio formats, and may be controlled with the I2C interface. These integrated high-performance features, together with the capability to be powered from a single-supply of 3.3V or 1.8V, make the device an excellent choice for space-constrained audio systems in far-field microphone recording applications.
The device is specified from –40C to +125C and is provided in a 20-pin WQFN package.
