ADS8341E/2K5 datasheet by Texas Instruments

ADS8341E/2K5 Frequently Asked Questions (FAQs)

• What is the recommended power-on sequence for the ADS8341E/2K5?
  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 ADS8341E/2K5 to minimize noise and ensure accurate conversions?
  To optimize the layout, keep the analog and digital grounds separate, use a solid ground plane, and keep the analog input traces short and away from digital signals. Also, use a low-ESR capacitor for the AVCC pin and a 0.1uF capacitor for the VREF pin.
• What is the maximum sampling rate I can achieve with the ADS8341E/2K5?
  The maximum sampling rate of the ADS8341E/2K5 is 100kSPS. However, the actual sampling rate may be limited by the system's clock frequency, analog input bandwidth, and other system-level factors.
• How do I handle the output data format of the ADS8341E/2K5?
  The ADS8341E/2K5 outputs 16-bit data in a binary two's complement format. The most significant bit (MSB) is the sign bit, and the remaining 15 bits represent the magnitude of the input signal.
• What is the purpose of the VREF pin on the ADS8341E/2K5, and how do I connect it?
  The VREF pin is the reference voltage input for the ADC. Connect a 2.5V voltage source to the VREF pin, and ensure it is decoupled with a 0.1uF capacitor to ground.
