Additionally, external calibration can be performed using an external voltage reference and adjusting the offset and gain registers. Refer to the datasheet and application notes for detailed calibration procedures.
• What is the maximum sampling rate that can be achieved with the ADC121S021CISD?
  The maximum sampling rate of the ADC121S021CISD is 1 MSPS (million samples per second). However, the actual sampling rate may be limited by the system clock frequency, conversion mode, and other factors. Refer to the datasheet and application notes for detailed information on sampling rate limitations.
• How do I handle overvoltage and undervoltage conditions with the ADC121S021CISD?
  The ADC121S021CISD has built-in overvoltage and undervoltage detection capabilities. The device can be configured to generate an interrupt or flag when an overvoltage or undervoltage condition is detected. Additionally, external protection circuits can be implemented to prevent damage to the device.
• What is the power consumption of the ADC121S021CISD, and how can I minimize it?
  The power consumption of the ADC121S021CISD varies depending on the operating mode, sampling rate, and other factors. The typical power consumption is around 1.5 mA at 1 MSPS. To minimize power consumption, use the lowest possible sampling rate, disable unnecessary features, and use the power-down mode when not in use.
