ADS7817EB/250 datasheet by Texas Instruments

ADS7817EB/250 Frequently Asked Questions (FAQs)

• What is the recommended layout and routing for the ADS7817EB/250 to achieve optimal performance?
  Texas Instruments provides a layout guide in the application note SLAA382, which includes recommendations for PCB layout, component placement, and routing to minimize noise and ensure optimal performance.
• How do I calibrate the ADS7817EB/250 to achieve high accuracy?
  The ADS7817EB/250 has an internal calibration circuit, but it may require external calibration for high-accuracy applications. TI provides a calibration procedure in the application note SLAA384, which includes steps for offset and gain calibration.
• What is the maximum sampling rate I can achieve with the ADS7817EB/250?
  The maximum sampling rate of the ADS7817EB/250 is 250 kSPS, but it depends on the clock frequency and the conversion mode. Refer to the datasheet for specific details on sampling rates and conversion modes.
• Can I use the ADS7817EB/250 with a 5V power supply?
  No, the ADS7817EB/250 is designed to operate with a 2.7V to 5.5V power supply, but it is not recommended to use it with a 5V power supply as it may exceed the maximum rating. It's recommended to use a 3.3V or 3.6V power supply for optimal performance.
• How do I handle the digital output data from the ADS7817EB/250?
  The ADS7817EB/250 outputs 16-bit digital data in a serial format. The data can be handled using a microcontroller or an FPGA, and TI provides example code and interface guidelines in the application note SLAA385.
