ADS7805U/1K Frequently Asked Questions (FAQs)

  • The maximum input voltage that can be applied to the ADS7805U/1K is 36V, but it's recommended to keep it below 30V for reliable operation.
  • To ensure accuracy, make sure to follow proper PCB layout guidelines, use a low-noise power supply, and minimize digital noise coupling to the analog inputs. Also, use the recommended capacitor values for the analog input filter.
  • The CAP pin is used to connect a capacitor to filter the internal reference voltage. Connect a 10nF to 100nF capacitor between the CAP pin and GND to improve the noise rejection and stability of the internal reference voltage.
  • Yes, the ADS7805U/1K can be used in a multi-channel application. However, you'll need to use an external multiplexer to select the desired channel and connect it to the ADC input. Make sure to follow proper channel switching and settling time guidelines to ensure accurate conversions.
  • The POR and BOR features are enabled by default. To handle them, ensure that your system design can tolerate the reset pulse duration (typically 10ms) and that your firmware can handle the reset event. You can also disable these features by tying the POR/BOR pin to VCC or GND, but this is not recommended.
