Working Principles
The TC7107ARCPL is a 3.5-digit analog-to-digital converter that utilizes dual-slope integration conversion. It integrates the reference and clock circuitry, simplifying system design and reducing component count. The device operates by integrating the input voltage for a fixed period and then discharging it through a known resistor. The resulting charge transfer is proportional to the input voltage and is converted into a digital output.
