Applications
The TC7107CPL is a classic choice for digital panel meters, bench multimeters, and industrial measurement instruments where a self-contained 3.5-digit readout is needed without a microcontroller. Its dual-slope integration technique provides inherent rejection of power-line frequency noise, making it reliable in environments with 50 Hz or 60 Hz interference common in factory and laboratory settings.

Frequently Asked Questions
How does the dual-slope conversion method in TC7107CPL improve measurement accuracy in AC-noisy environments?
The TC7107CPL uses a dual-slope integration technique, where the unknown input is integrated for a fixed period and then discharged at a known rate. This method inherently cancels noise at multiples of the integration time, providing strong 50 Hz and 60 Hz rejection. The result is accurate 3.5-digit readings even in industrial panels and lab instruments exposed to power-line interference.
Can the TC7107CPL directly drive a 7-segment LED display without additional decoder ICs?
Yes. The TC7107CPL includes on-chip segment and digit drivers designed to directly interface with common-anode 7-segment LED displays. The 40-pin PDIP package provides the necessary output pins for a complete 3.5-digit display, reducing BOM count and simplifying PCB layout for digital panel meter designs compared to ADCs requiring external decoder chips.
What is the lead time and package option for TC7107CPL in production quantities?
TC7107CPL carries a factory lead time of approximately 6 weeks in the 40-pin PDIP through-hole package. The device is RoHS-compliant (Pb-free, JESD-609 e3) and has a YTEOL of 8 years, indicating continued active availability. Designers evaluating compact PCB formats should check whether an SMT equivalent such as a PLCC or SOIC version meets their space requirements.
