ADS8343E/2K5 datasheet by Texas Instruments

ADS8343E/2K5 Frequently Asked Questions (FAQs)

• What is the recommended layout and routing for the ADS8343E/2K5 to minimize noise and ensure accurate conversions?
  Texas Instruments provides a layout and routing guide in the application note SLAA332, which recommends keeping the analog and digital grounds separate, using a solid ground plane, and minimizing the length of the analog input traces.
• How do I calibrate the ADS8343E/2K5 to achieve the highest accuracy?
  The ADS8343E/2K5 has an internal calibration circuit that can be used to calibrate the device. The calibration process involves applying a known input voltage and then reading the output code. The device can then be calibrated by adjusting the internal offset and gain registers.
• What is the maximum sampling rate that can be achieved with the ADS8343E/2K5?
  The maximum sampling rate of the ADS8343E/2K5 is 100 kSPS, but this can be limited by the system clock frequency, the conversion mode, and the interface mode. The datasheet provides more information on the sampling rate limitations.
• Can the ADS8343E/2K5 be used in a multi-channel application?
  Yes, the ADS8343E/2K5 can be used in a multi-channel application by using multiple devices or by using a multiplexer to switch between multiple input channels. However, the device does not have a built-in multiplexer, so an external multiplexer would be required.
• What is the power consumption of the ADS8343E/2K5, and how can it be minimized?
  The power consumption of the ADS8343E/2K5 is typically around 15 mW at 3 V and 100 kSPS. Power consumption can be minimized by reducing the clock frequency, using the power-down mode, and optimizing the system design to reduce the number of conversions required.
