ADC0804CN datasheet by Texas Instruments

ADC0804CN Frequently Asked Questions (FAQs)

• What is the maximum clock frequency for the ADC0804CN?
  The maximum clock frequency for the ADC0804CN is 640 kHz. However, it's recommended to operate the clock frequency between 100 kHz to 500 kHz for optimal performance.
• How do I handle the output data from the ADC0804CN?
  The ADC0804CN outputs data in a serial format, with the most significant bit (MSB) first. You'll need to use a microcontroller or a dedicated IC to latch and decode the output data. You can also use a shift register to convert the serial data to parallel format.
• What is the conversion time for the ADC0804CN?
  The conversion time for the ADC0804CN is approximately 100 μs. This is the time it takes for the ADC to complete one conversion cycle.
• Can I use the ADC0804CN with a single supply voltage?
  Yes, the ADC0804CN can operate with a single supply voltage between 5V to 15V. However, the analog input voltage range is limited to 0V to VCC (supply voltage). If your analog input signal is bipolar or has a negative voltage, you'll need to use a level shifter or an op-amp to condition the signal.
• How do I ensure accurate conversions with the ADC0804CN?
  To ensure accurate conversions, make sure to follow proper PCB layout and grounding techniques, use a stable clock source, and minimize noise on the analog input lines. You should also consider using a voltage reference IC to provide a stable reference voltage to the ADC.
