ADS8344N/1K datasheet by Texas Instruments

ADS8344N/1K Frequently Asked Questions (FAQs)

• What is the recommended power-on sequence for the ADS8344N/1K?
  The recommended power-on sequence is to apply VCC first, followed by AVCC, and then the analog input signal. This sequence helps prevent latch-up and ensures proper device operation.
• How do I optimize the layout for the ADS8344N/1K to minimize noise and ensure accurate conversions?
  To minimize noise and ensure accurate conversions, keep the analog input traces short and away from digital traces. Use a solid ground plane, and decouple the power supplies with 0.1uF and 10uF capacitors. Also, consider using a separate analog ground plane and connecting it to the digital ground plane at a single point.
• What is the maximum sampling rate I can achieve with the ADS8344N/1K?
  The maximum sampling rate of the ADS8344N/1K is 100kSPS. However, the actual sampling rate may be limited by the system's clock frequency, analog input bandwidth, and other factors. Consult the datasheet and application notes for more information.
• How do I handle the output data from the ADS8344N/1K? Is it in binary or two's complement format?
  The ADS8344N/1K outputs data in straight binary format. The most significant bit (MSB) is the sign bit, and the remaining bits represent the magnitude of the conversion result.
• What is the purpose of the REFOUT pin on the ADS8344N/1K, and how do I use it?
  The REFOUT pin provides a buffered reference voltage output that can be used as a reference for other devices in the system. Connect a 0.1uF capacitor from REFOUT to GND to filter the reference voltage and reduce noise.
