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.
