The LM358 is a dual operational amplifier that runs from a single power supply and senses all the way down to ground. This guide covers the pinout, specs that actually constrain your design, the output stage behaviour that catches engineers out, and worked circuit examples.
An instrumentation amplifier is a precision differential amplifier designed to amplify small voltage differences. This guide explains the three-op-amp architecture, and how to choose between INA128, AD620, LT1167, and a standard difference amplifier for sensor front-ends.
Every embedded design needs a clock, but not every clock needs the same source. This guide compares bare quartz crystals against packaged crystal oscillators, including TCXO, OCXO, VCXO, and MEMS variants, to help engineers pick the right timing component.
Current division is the principle that determines how electric current splits between parallel branches according to their resistance. This guide explains how to calculate the exact current in each branch using Ohm's law and Kirchhoff's current law, with practical examples and limitations.
The Seebeck effect converts a temperature difference across a conductor or junction of two materials into a voltage. This article reviews the physics, Seebeck coefficients, thermoelectric materials, figure of merit, thermocouples, and generator design.
A Schmitt trigger is a comparator circuit with built-in hysteresis that uses two switching thresholds to eliminate noise and ensure stable output transitions. It is widely used for signal conditioning, waveform shaping, and robust digital and analog circuit design.
