ADC0844CCN datasheet by Texas Instruments

ADC0844CCN Frequently Asked Questions (FAQs)

• What is the recommended input impedance for the ADC0844CCN?
  The recommended input impedance for the ADC0844CCN is 1 kΩ to 10 kΩ. This ensures proper signal attenuation and prevents signal reflections.
• How do I handle the ADC0844CCN's analog input voltage range?
  The ADC0844CCN's analog input voltage range is 0 to VREF (typically 2.5V or 5V). Ensure that the input signal is within this range to avoid saturation or clipping.
• What is the purpose of the VREF pin on the ADC0844CCN?
  The VREF pin sets the reference voltage for the ADC. It determines the full-scale range of the ADC. Typically, VREF is connected to a stable voltage source, such as a voltage regulator or a bandgap reference.
• How do I convert the ADC0844CCN's output code to a voltage value?
  To convert the ADC output code to a voltage value, use the following formula: Voltage = (Output Code / 2^n) * VREF, where n is the number of bits (in this case, 8 bits).
• What is the maximum sampling rate of the ADC0844CCN?
  The maximum sampling rate of the ADC0844CCN is 200 kHz. However, this rate may vary depending on the specific application and system constraints.
