Order now


The PCMD3140 evaluation module (EVM) performance demonstration kit (PDK) allows the user to test the capabilities of the PCMD3140. PCMD3140 is a high-performance, pulse-density modulation (PDM) input to time-division multiplexing (TDM) or inter-IC sound (I2S) output converter that supports simultaneous sampling of up to four digital channels for the PDM microphone input.

The PCMD3140 EVM is paired with the AC-MB (included in the kit), a flexible audio converters motherboard that provides power, control, and digital audio data to the EVM.
