      If you look at the chip's datasheet you'll see its input bandwidth is 15kHz for -3dB drop. Section 6.5 electrical characteristics, so what you see is correct. You can see the low pass filter in the chip's block diagram too. If you want an...

      Ruksitakam replied to the thread Using Teensy4.1 with external ADC (ADS8681).
      I am planning to use an external ADC with the Teensy 4.1 for my Acoustic Emission project, where I need to detect crack frequencies around 150kHz. According to the Nyquist theorem, this requires a sampling rate of at least 300kHz. With the...

      Ruksitakam posted the thread Using Teensy4.1 with external ADC (ADS8681) in Project Guidance.
      In this project, I used a Teensy 4.1 microcontroller to interface with the ADS8681 analog-to-digital converter (ADC) via SPI to perform high-speed data acquisition and log the results to an SD card. The objective was to collect 1000 samples...
