PCM6240-Q1 4-ch audio ADC with integrated programmable microphone bias evaluation module


Order now


The PCM6240-Q1 evaluation module (EVM) performance demonstration kit (PDK) allows the user to test the capabilities of the PCM6240-Q1 device, which is a a four-channel, high-performance audio analog-to-digital converter (ADC) that supports analog input signals up to 10 VRMS.

PCM6240-Q1 supports line and microphone inputs for single-ended and differential input configurations. The device offers integrated high voltage, programmable microphone bias, and integrated diagnostic circuitry that allows direct connections to microphone-based automotive systems with fault capability for dc-coupled inputs.

PCM6240Q1EVM-PDK 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.
