Description of product

PCMD3180 8-Channel Audio ADC

Texas Instruments PCMD3180 8-Channel Audio Analog-to-Digital Converter (ADC) is a high-performance, pulse-density-modulation (PDM) input to time-division multiplexing (TDM) or I2S output converter. It supports simultaneous sampling of up to eight digital channels for the PDM microphone input. The device integrates programable digital volume control, a microphone bias voltage, and a phase-locked loop (PLL). It also includes a programmable high-pass filter (HPF), biquad filters, low-latency filter modes, and allows for output sample rates up to 768kHz. The Texas Instruments PCMD3180 supports time-division multiplexing (TDM), I2S, or left-justified (LJ) audio formats, and can be controlled with either the I2C or SPI interfaces. Additionally, the PCMD3180 supports master and slave mode selection for the audio bus interface operation. These integrated high-performance features, along with the ability 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 Texas Instruments PCMD3180 is specified from –40°C to +125°C and is available in a 24-pin WQFN package.
