The TAA3020 is a high-performance, audio analog-to-digital converter (ADC) that supports simultaneous sampling of up to two analog channels or four digital channels for a pulse density modulation (PDM) microphone input. The device supports line and microphone inputs and allows single-ended and differential input configurations. The device allows for sample rates up to 768kHz and 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, and low-latency filter modes. 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 and the ability to be powered from a single supply of 1.8V or 3.3V make the device an excellent choice for space-constrained audio systems in far-field microphone recording applications.
The TAA3020 is specified from –40°C to +105°C, and is offered in a 20-pin WQFN package.
