ADS7824P datasheet by Texas Instruments

ADS7824P Frequently Asked Questions (FAQs)

• What is the maximum sampling rate of the ADS7824P?
  The maximum sampling rate of the ADS7824P is 250 kHz, but it can be limited by the conversion time, which is typically around 1.5 μs.
• How do I handle the output data format of the ADS7824P?
  The ADS7824P outputs data in a 16-bit, two's complement format. You can handle this by using a microcontroller or FPGA to read the data and convert it to a more usable format, such as unsigned integer or floating-point.
• What is the recommended power supply decoupling for the ADS7824P?
  Texas Instruments recommends using a 0.1 μF ceramic capacitor and a 10 μF tantalum capacitor in parallel to decouple the power supply pins (VCC and GND) of the ADS7824P.
• Can I use the ADS7824P in a multiplexed configuration?
  Yes, the ADS7824P can be used in a multiplexed configuration, but you need to ensure that the multiplexer is fast enough to switch between channels within the conversion time of the ADC. You also need to consider the settling time of the input signal and the multiplexer.
• How do I calibrate the ADS7824P?
  The ADS7824P does not require calibration, as it has an internal calibration circuit that is performed during power-up. However, you may need to perform system-level calibration to account for any offsets or gains in your specific application.
