ADC108S102CIMTX/NOPB datasheet by Texas Instruments

ADC108S102CIMTX/NOPB Frequently Asked Questions (FAQs)

• What is the recommended input impedance for optimal performance?
  The recommended input impedance is 1 kΩ to 10 kΩ. This ensures that the input signal is properly terminated and minimizes signal reflections.
• How do I ensure accurate conversion results in noisy environments?
  To ensure accurate conversion results in noisy environments, use a low-pass filter at the input to remove high-frequency noise, and consider using a shielded cable to connect the input signal to the ADC.
• What is the maximum sampling rate I can achieve with this ADC?
  The maximum sampling rate of the ADC108S102CIMTX/NOPB is 500 kSPS. However, the actual achievable sampling rate may be limited by the system's clock frequency and the ADC's conversion time.
• Can I use this ADC with a single-ended input signal?
  Yes, the ADC108S102CIMTX/NOPB can be used with a single-ended input signal. However, the input signal should be biased around the midpoint of the ADC's input range to ensure optimal performance.
• How do I handle overvoltage conditions at the input?
  To handle overvoltage conditions, use external protection circuitry such as voltage-limiting resistors or clamping diodes to prevent damage to the ADC. Additionally, consider using a voltage regulator to regulate the input voltage.
