AD7849ANZ Frequently Asked Questions (FAQs)

  • A good layout and routing practice is to keep the analog and digital grounds separate, use a solid ground plane, and keep the analog signals away from the digital signals. Also, use short and direct traces for the analog signals, and avoid crossing digital signals over the analog signals.
  • The AD7849ANZ is a versatile device that can be configured for various applications. For a touch screen or resistive touchscreen, you'll need to set the correct gain, offset, and calibration settings. Refer to the application notes and evaluation boards provided by Analog Devices Inc for specific configuration guidelines.
  • The AD7849ANZ operates from -40°C to +85°C. Temperature affects the device's performance, particularly the accuracy and linearity of the ADC. Ensure proper thermal management and consider the temperature coefficient when designing your system.
  • To minimize EMI and ensure EMC, use proper shielding, grounding, and filtering techniques. Keep the AD7849ANZ away from high-frequency sources, and use a low-pass filter on the analog inputs. Also, follow the recommended layout and routing guidelines to reduce radiation and susceptibility.
  • The recommended power-up sequence is to apply the analog power supply (VCC) first, followed by the digital power supply (VDD). Ensure that the analog power supply is stable before applying the digital power supply. Also, ensure that the reset pin (RST) is properly driven during power-up.
