Texas Instruments ADCx120Q1EVM-PDK & PCMD3140Q1EVM-PDK Eval Modules

Texas Instruments ADCx120Q1EVM-PDK and PCMD3140Q1EVM-PDK Evaluation Modules are optimal to test the capabilities of the PCM3120-Q1 and PCMD3140-Q1 devices. The PCM3120-Q1 device is a stereo, high-performance audio analog-to-digital converter (ADC) intended for voice-activated systems, professional microphones, audio conferencing, portable computing, communication, and entertainment applications. The TI PCMD3140-Q1 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 four digital channels for the PDM microphone input.

The TI ADCx120Q1EVM-PDK and PCMD3140Q1EVM-PDK Eval Modules are paired with the AC-MB, a flexible motherboard that provides power, control, and digital audio data to the EVM.
