ADS8361IDBQG4 datasheet by Texas Instruments

ADS8361IDBQG4 Frequently Asked Questions (FAQs)

• What is the recommended layout and routing for the ADS8361IDBQG4?
  Texas Instruments provides a layout guide and PCB design checklist in the ADS8361 datasheet, which includes recommendations for component placement, routing, and grounding to minimize noise and ensure optimal performance.
• How do I calibrate the ADS8361IDBQG4?
  The ADS8361IDBQG4 does not require calibration. It has an internal calibration circuit that sets the gain and offset of the ADC. However, users can perform a system-level calibration by applying a known input voltage and adjusting the digital output to match the expected value.
• What is the maximum input voltage range for the ADS8361IDBQG4?
  The ADS8361IDBQG4 has a maximum input voltage range of ±VREF (±2.5V typical) for the differential input mode and ±VCC (±5V typical) for the single-ended input mode. Exceeding these limits can damage the device.
• How do I handle overvoltage protection for the ADS8361IDBQG4?
  The ADS8361IDBQG4 has internal overvoltage protection up to ±16V. However, it is recommended to add external protection circuitry, such as voltage-limiting resistors or clamping diodes, to prevent damage from high-voltage transients or faults.
• What is the power-on reset (POR) timing for the ADS8361IDBQG4?
  The ADS8361IDBQG4 has a built-in POR circuit that resets the device after power-up. The POR timing is typically 10ms, but it can vary depending on the power supply ramp rate and other factors. Users should ensure that the device is properly reset before starting conversions.
