Issues measuring fast signals on the nRF54L15-DK ADChttps://devzone.nordicsemi.com/f/nordic-q-a/126843/issues-measuring-fast-signals-on-the-nrf54l15-dk-adcHello, I am trying to measure a fast, impulsive signal from an amplified analog microphone using an ADC pin on the nRF54L15-DK. When I read the same signal using a 12-bit analog input on an Arduino board (ESP32 Feather V2), the waveform behaves as expecteden-USTelligent Community 13Wed, 04 Feb 2026 08:41:52 GMTRE: Issues measuring fast signals on the nRF54L15-DK ADChttps://devzone.nordicsemi.com/thread/560305?ContentTypeID=1Wed, 04 Feb 2026 08:41:52 GMT137ad170-7792-4731-bb38-c0d22fbe4515:275c5b3e-90f4-4651-b022-bdb6dddc8a7fKenneth<p>Also you can download the board control app in nRF Connect for Desktop to control the board (e.g. supply voltage):<br /><a href="https://docs.nordicsemi.com/bundle/ug_nrf54l15_dk/page/UG/nRF54L15_DK/hw_desription/board_control.html">https://docs.nordicsemi.com/bundle/ug_nrf54l15_dk/page/UG/nRF54L15_DK/hw_desription/board_control.html</a>&nbsp;</p> <p>Kenneth</p><div style="clear:both;"></div>RE: Issues measuring fast signals on the nRF54L15-DK ADChttps://devzone.nordicsemi.com/thread/560292?ContentTypeID=1Wed, 04 Feb 2026 07:38:21 GMT137ad170-7792-4731-bb38-c0d22fbe4515:9f3dc8e9-c7ab-4500-8c0e-6058bd4f1198Turbo J<p>Check the DK schematic. Looks to me like there is another component connected to the pin like an LED, which clips your input signal.</p> <p>Won&#39;t clip a bench supply - but it should light up in that case.</p><div style="clear:both;"></div>
