ADC12138CIMSAX/NOPB Frequently Asked Questions (FAQs)

  • The recommended input impedance for the ADC12138 is between 1 kΩ and 10 kΩ to ensure proper operation and minimize signal attenuation.
  • To optimize the analog input range, adjust the VREF pin to set the full-scale range of the ADC. The VREF pin can be connected to a voltage reference or a resistive divider network to set the desired input range.
  • The maximum sampling rate of the ADC12138 is 1 MSPS. Increasing the sampling rate will increase power consumption, so it's essential to balance sampling rate with power consumption requirements for your specific application.
  • To ensure accurate conversions, use a low-noise, low-impedance analog input signal, and ensure the analog input signal is properly filtered and buffered. Additionally, use a stable clock source and ensure the ADC is properly calibrated.
  • The CAL pin is used for calibration and offset correction. Connect the CAL pin to a voltage reference or a resistive divider network to set the calibration voltage. During calibration, the ADC12138 will adjust its internal offset to match the calibration voltage.
