ADS8681IRUMT Frequently Asked Questions (FAQ)

  • Texas Instruments recommends a 4-layer PCB with a solid ground plane, and to keep the analog and digital signals separate. The datasheet provides a recommended layout and routing guide, but it's also recommended to consult the TI application note 'AN-1187: PCB Layout Guidelines for Switching Regulators' for more detailed information.

  • To optimize the performance of the ADS8681IRUMT, it's recommended to follow the guidelines in the datasheet and application notes. Additionally, consider the following: use a low-ESR capacitor for the analog supply, minimize the distance between the ADC and the analog signal source, and use a low-noise power supply. It's also recommended to consult with TI's technical support team for specific guidance on optimizing performance in your application.

  • The maximum sampling rate of the ADS8681IRUMT is 1 MSPS (million samples per second). However, the actual achievable sampling rate may be limited by the system's clock frequency, the analog input signal's bandwidth, and the system's noise floor.

  • The ADS8681IRUMT outputs 16-bit digital data in a serial format. The data can be handled using a microcontroller or an FPGA. The datasheet provides information on the data format and timing, and TI also provides example code and software development kits (SDKs) to help with data handling and processing.

  • The power consumption of the ADS8681IRUMT depends on the operating mode and the sampling rate. In normal operation, the device consumes around 35 mW at 1 MSPS. In power-down mode, the device consumes around 10 μW. The datasheet provides more detailed information on power consumption and power management.
