ADS7865IPBSR Frequently Asked Questions (FAQs)

  • The recommended power-up sequence is to apply VDD first, followed by AVDD, and then the digital supply (DVDD). This ensures proper operation and prevents latch-up.
  • To optimize the analog input impedance, use a low-impedance source, such as a buffer amplifier, and keep the input traces as short as possible. Additionally, use a capacitor (e.g., 10nF) in parallel with a resistor (e.g., 1kΩ) to filter out high-frequency noise.
  • The maximum sampling rate for the ADS7865 is 250 kSPS (kilosamples per second) for a single channel, and 125 kSPS for multiple channels.
  • The ADS7865 outputs 16-bit data in two's complement format. To handle the data, use a microcontroller or FPGA to read the data and perform any necessary processing, such as scaling or averaging.
  • The REF pins (REFP and REFN) are used to set the analog reference voltage for the ADC. Connect a stable voltage source (e.g., 2.5V) to these pins to set the full-scale range of the ADC.
