Featured Tools

Instrumentation Amplifier Gain Calculator

The instrumentation amplifier calculator will assist in the design and analysis of a conventional instrumentation amplifier circuit by calculating the required resistor values and gain.

Analog Calculators & Tools

Lorentz Force Calculator

This calculator will determine the combined Lorentz force exerted on a charged particle moving through both an electric field and a magnetic field.

Parallel Resistor Calculator

Calculate the equivalent resistance of up to six resistors in parallel with ease while learning how to calculate resistance in parallel and the parallel resistance formula.

Wheatstone Bridge Calculator

This calculator helps determine the resistance of a variable resistor within a Wheatstone bridge circuit or the differential voltage created across the bridge terminals.

Electrical Energy Calculator

This calculator will determine the instantaneous energy, sustained energy, and power consumed by an electrical system given two of the three electrical parameters (voltage, current, or resistance) and the time.

Battery Life Calculator

This calculator provides three options—basic, intermediate, and advanced—for determining expected battery life for microcontroller, Internet of Things (IoT), and edge processing systems with up to four different operating modes.

Decibel Calculator

This calculator will convert voltage or power gains into decibels. Enter one of the three values and the calculator will output the other two.

Square Root, Cube Root, and Nth Root Calculator

This calculator will determine the square root, cube root, or nth root of a given number, x.

LC Resonant Frequency Calculator

A circuit with an inductor (L) and capacitor (C) connected in parallel or series will have a resonant frequency at which their impedances are equal. Given two of the three values—inductance, capacitance, or resonant frequency—this tool will calculate the missing third variable.

RC Time Constant Calculator

The time constant of a series RC circuit is the product of the resistance and capacitance. Given two of the three values—resistance, capacitance, or RC time constant—this tool will calculate the missing third variable.

Comparator with Hysteresis (Schmitt Trigger) Calculator

This calculator will compute the required resistor ratio (R2/R1) and reference voltage (VREF) to create the desired high (VTH) and low (VTL) threshold voltages in a non-inverting comparator circuit with hysteresis (commonly called a Schmitt trigger).
