The LM195 and LM395 are both high efficiency power transistors that were initially manufactured by National Semiconductor Corporation, and later acquired by “Texas Instruments”. These special power transistors are intended to be used in high power switching applications, where low power dissipation and high current gain are critical parameters. These special power transistors are virtually […]
Newly Updated Circuit Projects:
Simple Voltage Multiplier Circuits Explored
In this article I have explained how an input AC source could be increased to any desired levels using simple voltage multiplier circuits, built with capacitors and diodes. Thus the basic function of a voltage multiplier circuit is to multiply a given AC voltage source to any higher desired level, simply by adding the relevant […]
LM311 Datasheet, Circuit Applications
The LM311 is a versatile, fast voltage comparator with multiple capabilities. Its output stage is “open collector” and “open emitter,” allowing for various configurations. It can directly control relays and its output can be compatible with several logics, including TTL. Technical Specifications and Datasheet Here are some of the technical specifications of the LM311 comparator […]
Proximity Detector using Hall Effect Sensor Circuit
This proximity detector circuit uses a Hall effect sensor to detect the approach of a magnetic object, such as a magnet fixed to the frame of a door. The application is simple, but widely used. The use of a Hall effect sensor solves many problems that arise when one wants to detect the opening of […]
Anti-Corrosion Probes for Water Level Controller
In this post I have explained a few interesting methods of constructing anti-corrosion probes for water level sensor and controller circuits by using alternating supply across the probes. Using Bridge Rectifiers (New Update) This simple anti-corrosion probe idea using bridge rectifiers happened to strike me recently and I decided to post it here for you […]
Parametric Equalizer Circuit
In this post we talk about a parametric equalizer circuit which can be used to enhance a music output to outstanding levels, much better than any standard graphic equalizer output. Advantages The main advantage of a parametric equalizer is that it allows you to modify the frequency and the “Q factor” across a wide range while also […]
