- **Auto-Zero Function:** Ensures accurate zero readings  
- **Low Power Consumption:** Ideal for battery-powered devices  
- **On-Chip LCD Driver:** Eliminates the need for external drivers  
- **True Polarity Indication:** Displays positive and negative values  
- **Low Noise:** Improves measurement accuracy  
- **Directly Interfaces with LCDs:** Simplifies design  

This device is commonly used in digital multimeters, scales, and other measurement instruments.

Application Scenarios & Design Considerations

3-1/2 DIGIT ANALOG-TO-DIGITAL CONVERTERS WITH HOLD

Alternative Part Number

  • ICL7116CPL --: Pin-compatible 3.5-digit ADC with display hold, functionally equivalent to the TC7116 and widely available.
  • MAX131CPL --: Similar 3.5-digit ADC with hold function in a 40-pin DIP, suitable as a functional replacement with minor circuit review.
  • ICL7106CPL --: Same 3.5-digit ADC family in a 40-pin DIP; lacks the hold pin but works as a drop-in substitute when hold is not required.
