ADS7804UB Frequently Asked Questions (FAQs)

  • The ADS7804UB requires careful layout and routing to minimize noise and ensure accurate conversions. TI recommends using a 4-layer PCB with a solid ground plane, keeping analog and digital traces separate, and using a common mode filter to reduce noise.
  • The ADS7804UB outputs 16-bit data in two's complement format. The most significant bit (MSB) represents the sign bit, and the remaining 15 bits represent the magnitude. You can use a microcontroller or FPGA to process the output data.
  • The ADS7804UB can operate with a clock frequency between 1 MHz and 4 MHz. However, TI recommends using a clock frequency of 2.4576 MHz for optimal performance.
  • The ADS7804UB does not require calibration. It has an internal calibration circuit that ensures accurate conversions. However, you may need to perform system-level calibration depending on your specific application.
  • The ADS7804UB has a power-on reset (POR) circuit that resets the device when the supply voltage rises above 1.5 V. The POR circuit ensures that the device starts in a known state after power-up.
