ISD1820 Voice Recording IC Datasheet, Circuit Diagram
The ISD1820 is a voice IC that lets us record voice from a mic and play it back using simple buttons or microcontroller. We can record between 8 to 20 seconds which depends on how we set it. This IC is used in small voice projects, talking toys, greeting circuits, voice alerts, and more. ISD1820 […]
ACS712 Current Sensor Circuit Diagrams and Datasheet
Here we are going to learn one cool and very important current sensor device which we call ACS712. This small chip that look just like a normal 8-pin IC, is actually able to sense current from any load and give us a proportional analog voltage output which we can easily feed to Arduino or any […]
How IC LM337 Works: Datasheet, Application Circuits
In this post I will talk about the function of an interesting voltage regulator device: The LM337, which is basically the negative complementary device for the popular LM317 IC. Built with an adjustable 3-terminal negative voltage, this regulator can conveniently supply around 1.5 A with an output voltage range of -1.2 V to -37 V. […]
