ADS7841ES/2K5 datasheet by Texas Instruments

ADS7841ES/2K5 Frequently Asked Questions (FAQs)

• What is the recommended power-up sequence for the ADS7841?
  The recommended power-up sequence is to apply VCC first, followed by VREF, and then the clock signal. This ensures proper initialization of the device.
• How do I handle the busy signal (BUSY) during conversion?
  The BUSY signal goes high during conversion and remains high until the conversion is complete. The host should wait for BUSY to go low before accessing the conversion result.
• What is the maximum sampling rate for the ADS7841?
  The maximum sampling rate for the ADS7841 is 125 kHz. However, the actual sampling rate may be limited by the clock frequency and the conversion time.
• How do I calibrate the ADS7841 for optimal performance?
  The ADS7841 has an internal calibration circuit that can be used to calibrate the device. The calibration process involves applying a known input voltage and adjusting the internal calibration registers to achieve optimal performance.
• What is the effect of temperature on the ADS7841's performance?
  The ADS7841's performance is affected by temperature, with changes in offset, gain, and noise performance. The device is specified to operate over a temperature range of -40°C to 85°C.
