The PCMD3180 is a high-performance, pulse-density-modulation (PDM) input to time-division multiplexing (TDM) or I2S output converter that supports simultaneous sampling of up to eight digital channels for the PDM microphone input. The device integrates programmable digital volume control, a microphone bias voltage, a phase-locked loop (PLL), a programmable high-pass filter (HPF), biquad filters, low-latency filter modes, and allows for output 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. 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 PCMD3180 is specified from –40°C to +125°C, and is offered in a 24-pin WQFN package.
