ADC121S625CIMM/NOPB Frequently Asked Questions (FAQs)

• What is the recommended input impedance for the ADC121S625?
  The recommended input impedance for the ADC121S625 is between 1 kΩ and 10 kΩ to ensure proper operation and minimize signal attenuation.
• How do I optimize the ADC121S625's analog input range for my specific application?
  To optimize the analog input range, you should consider the voltage reference (VREF) and the analog input voltage range. The ADC121S625 has a default VREF of 2.5V, but you can adjust it to 1.5V or 4.096V using the VREF pin. Choose the VREF that best suits your application's input voltage range.
• What is the maximum sampling rate of the ADC121S625, and how does it affect power consumption?
  The maximum sampling rate of the ADC121S625 is 1 MSPS. As the sampling rate increases, power consumption also increases. To minimize power consumption, consider reducing the sampling rate or using the ADC's power-down mode when not in use.
• How do I handle the ADC121S625's digital output data format?
  The ADC121S625 outputs 12-bit digital data in a straight binary format. You can use the SPI-compatible interface to read the output data, which is available in MSB-first or LSB-first formats, depending on the configuration.
• What are the thermal considerations for the ADC121S625, and how do I ensure reliable operation?
  The ADC121S625 has an operating temperature range of -40°C to 125°C. Ensure reliable operation by keeping the device within this range, avoiding thermal gradients, and providing adequate heat dissipation in your design.
