ADC122S051QIMM/NOPB Frequently Asked Questions (FAQs)

• What is the recommended input impedance for the ADC122S051?
  The recommended input impedance for the ADC122S051 is 1 kΩ to 10 kΩ. This ensures proper signal attenuation and filtering.
• How do I optimize the ADC122S051's performance for low-frequency signals?
  To optimize the ADC122S051's performance for low-frequency signals, use a higher gain setting, increase the sampling rate, and implement a digital filter to reduce noise and aliasing.
• What is the maximum input voltage range for the ADC122S051?
  The maximum input voltage range for the ADC122S051 is VREFP to VREFN, which is typically 0 V to 5 V. Exceeding this range may result in inaccurate conversions or damage to the device.
• How do I handle overvoltage conditions on the ADC122S051's inputs?
  To handle overvoltage conditions, use external voltage limiting circuits, such as clamping diodes or voltage dividers, to prevent voltages exceeding the maximum input range from reaching the ADC inputs.
• What is the ADC122S051's latency, and how does it affect my system's performance?
  The ADC122S051's latency is approximately 1.5 clock cycles. This latency may affect system performance in high-speed applications. Consider using a FIFO or buffer to mitigate the impact of latency on your system.
