Frequently Asked Questions

What analog input voltage range does TC7107RCPL accept, and how does linearity error affect measurement accuracy?

TC7107RCPL accepts analog inputs from 3.5V to 5.5V with a maximum linearity error of 0.05%, delivering accurate 3.5-digit readings suitable for panel meters measuring millivolt-level signals in industrial instrumentation applications.

Can TC7107RCPL directly drive a multi-digit 7-segment LED display without additional driver ICs?

Yes, TC7107RCPL integrates an LED segment driver capable of sourcing current to standard 7-segment displays across up to 3.5 display digits, removing the need for separate driver transistors or ICs and simplifying the BOM to under 10 passive components.

Why is a -4.5V negative supply required for TC7107RCPL, and how is it typically generated on a single-supply board?

The -4.5V rail biases the internal comparator and integrator to handle analog inputs near ground (0V reference) with the full 3.5-digit dynamic range. A small charge-pump IC or a dual-output DC-DC converter generates this rail from a 5V supply, adding only 1-2 passive components to the design.

How does TC7107RCPL in a 40-pin DIP compare to its CMOS counterpart when choosing between LED and LCD display systems?

TC7107RCPL drives LED displays with active current outputs and requires a -4.5V negative supply, while the companion TC7106 variant drives LCD displays with AC-square-wave outputs at lower power. For benchtop instruments with high ambient light, TC7107RCPL's 1-channel LED drive at 5V is preferable despite the extra 4.5V rail.
