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 768kHz.
The device supports time-division multiplexing (TDM), I2S, or left-justified (LJ) audio formats, and can be controlled with either the I2C or SPI interface.
These integrated high-performance features, along with the ability to be powered from a single-supply of 3.3 or 1.8V, make the device an excellent choice for space-constrained audio systems in far-field microphone recording applications.
The TLV320ADC5140 is specified from -40 to +125°C, and is offered in a 24-pin WQFN package.
