ICL7107 [CS7107] - 3+1/2 Digit LED Driver with A/D

ICL7107 / CS7107: 3.5 Digit LED Driver with Integrated A/D Converter

The ICL7107/CS7107 is a high-performance, low-power 3.5 digit Analog-to-Digital converter. This versatile IC integrates essential components including seven-segment decoders, display drivers, a precision reference, and an on-chip clock. It is specifically designed to directly drive instrument-sized LED displays, significantly simplifying your design and reducing external component count. Benefit from guaranteed zero reading for 0V input across all scales, ensuring accurate measurements. True polarity at zero allows for precise null detection, critical in many applications. With low noise operation, typically less than 15µVP-P, and minimal power dissipation, this solution is both efficient and reliable. The ICL7107/CS7107 offers enhanced display stability without requiring additional active circuits, making it an ideal choice for a wide range of digital display projects.
