ADS7800KU Frequently Asked Questions (FAQs)

  • Texas Instruments provides a recommended layout and routing guide in the ADS7800KU evaluation module user's guide (SLAU445). It's essential to follow this guide to minimize noise, ensure proper signal integrity, and achieve optimal performance.
  • The ADS7800KU outputs 16-bit digital data in a binary two's complement format. Engineers should ensure that their microcontroller or digital signal processor can handle this format and perform any necessary data manipulation, such as scaling or offset correction.
  • Clock jitter can affect the ADS7800KU's performance, particularly in high-frequency applications. It's essential to use a low-jitter clock source and ensure that the clock signal is properly filtered and decoupled to minimize the impact of clock jitter.
  • The ADS7800KU requires a two-point calibration to achieve optimal accuracy. Engineers should perform a gain calibration and an offset calibration using known input voltages and the device's internal calibration registers.
  • The recommended power-up sequence for the ADS7800KU is to power up the analog supply (AVDD) first, followed by the digital supply (DVDD), and then the clock signal. This sequence helps to ensure proper device operation and minimize the risk of latch-up or other issues.
