ADC78H90CIMT/NOPB datasheet by Texas Instruments

ADC78H90CIMT/NOPB Frequently Asked Questions (FAQs)

• What is the recommended input impedance for optimal performance?
  The recommended input impedance is 1 kΩ to 10 kΩ. This ensures that the input signal is properly terminated and minimizes signal reflections.
• How do I handle the digital output data from the ADC?
  The ADC78H90CIMT/NOPB outputs 16-bit data in a binary two's complement format. You can use a microcontroller or FPGA to read and process the data. Make sure to follow the correct data format and timing diagrams provided in the datasheet.
• What is the maximum sampling rate I can achieve with this ADC?
  The ADC78H90CIMT/NOPB can achieve a maximum sampling rate of 500 kSPS (kilosamples per second). However, this may vary depending on the specific application and system design.
• How do I calibrate the ADC to ensure accurate conversions?
  The ADC78H90CIMT/NOPB has an internal calibration circuit that can be used to calibrate the ADC. You can also use external calibration methods, such as using a known voltage reference or a calibration signal. Refer to the datasheet for more information on calibration procedures.
• What is the power consumption of the ADC, and how can I minimize it?
  The typical power consumption of the ADC78H90CIMT/NOPB is around 35 mW. To minimize power consumption, you can use the ADC's power-down mode, reduce the sampling rate, or use a lower supply voltage. Additionally, you can use power-saving techniques such as dynamic voltage and frequency scaling.
