ADC1175CIJMX Frequently Asked Questions (FAQs)

• What is the recommended input impedance for the ADC1175?
  The recommended input impedance for the ADC1175 is 1 kΩ to 10 kΩ. This ensures that the input signal is properly terminated and minimizes signal reflections.
• How do I optimize the ADC1175's performance for low-frequency signals?
  To optimize the ADC1175's performance for low-frequency signals, use the internal buffer amplifier, set the gain to 1, and use a low-pass filter to remove high-frequency noise. Additionally, consider using an external anti-aliasing filter to further improve performance.
• What is the maximum sampling rate I can achieve with the ADC1175?
  The maximum sampling rate of the ADC1175 is 100 kSPS (kilosamples per second). However, this rate may be limited by the specific application, noise conditions, and the quality of the input signal.
• How do I handle overvoltage protection for the ADC1175?
  The ADC1175 has internal overvoltage protection up to ±16.5 V. However, it's still recommended to use external protection circuitry, such as voltage-limiting resistors or diodes, to prevent damage from excessive voltage spikes or transients.
• What is the power consumption of the ADC1175, and how can I minimize it?
  The power consumption of the ADC1175 varies depending on the operating mode and frequency. To minimize power consumption, use the lowest possible frequency, disable the internal buffer amplifier when not needed, and consider using the power-down mode when the ADC is not in use.
