ADC12040CIVY/NOPB datasheet by Texas Instruments

ADC12040CIVY/NOPB Frequently Asked Questions (FAQs)

• What is the recommended input impedance for the ADC12040?
  The recommended input impedance for the ADC12040 is 1 kΩ to 10 kΩ. This ensures proper signal attenuation and prevents signal reflections.
• How do I optimize the ADC's performance for low-frequency signals?
  To optimize the ADC's performance for low-frequency signals, use the internal buffer amplifier, and consider using an external RC filter to remove high-frequency noise. Also, ensure the input signal is within the ADC's input range.
• What is the maximum sampling rate I can achieve with the ADC12040?
  The maximum sampling rate of the ADC12040 is 200 kSPS. However, this rate may vary depending on the specific application, input signal, and system design.
• How do I handle the ADC's latency and pipelining?
  The ADC12040 has a pipeline delay of 12 clock cycles. To handle latency, consider using a FIFO or a buffer to store the converted data, and synchronize the data transfer with the ADC's conversion rate.
• What is the purpose of the ADC's internal reference voltage?
  The internal reference voltage (VREF) is used to set the full-scale range of the ADC. It can be bypassed using an external reference voltage, but this is not recommended as it may affect the ADC's performance and accuracy.
