Power Supply Connection:
- Connect the supply voltage (Vcc) to pin 16 and ground (GND) to pin 8. Ensure the supply voltage is within the specified range.
Reference Voltage Setup:
- The internal reference voltage can be used directly or externally set. For internal reference, connect REFLO to GND and REFGND to a low-impedance ground.
Input Signal Connection:
- Connect the analog signal to the IN+ and IN- pins. Ensure the impedance of the source is compatible with the input impedance of the ICL7107.
Display Driver Configuration:
- Configure the display driver connections according to the type of display being used (LED or LCD).
Calibration:
- Calibrate the zero and full-scale readings as per the application requirements. Adjust the reference voltage if necessary for accurate readings.
Temperature Compensation:
- Account for temperature drift in the setup if operating over a wide temperature range. Use the provided drift specifications to adjust readings accordingly.
Conversion Control:
- Manage the conversion rate based on the application needs. The typical conversion rate is 3 Hz but can be adjusted using external components.
Power Management:
- Monitor the power consumption and ensure it does not exceed the maximum allowable limit to avoid overheating and damage.
