ADS7846E/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 data.
  • The maximum frequency of the clock signal is 3.25 MHz. Exceeding this frequency may result in incorrect conversions or device malfunction.
  • The gain of the ADS7846E can be configured using the GAIN[1:0] pins. The gain settings are: 00 = 1x, 01 = 2x, 10 = 4x, and 11 = 8x.
  • The VREF pin is the reference voltage input for the ADC. It should be connected to a stable voltage source between 2.5V and 5V, depending on the desired full-scale input range.
