ADS7844E/2K5G4 Frequently Asked Questions (FAQs)

  • 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.
  • 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.
  • The maximum sampling rate for the ADS7844E is 125 kHz, but it can be limited by the clock frequency and the conversion mode used.
  • Yes, the ADS7844E can use an external reference voltage between 1.8V and 3.6V, but the input range and accuracy may be affected.
  • Calibration involves adjusting the offset and gain of the ADC to match the specific application requirements. TI provides a calibration procedure in the datasheet and application notes.
