Our project creates a versatile function generator using op-amps to generate sine, square, and triangular waveforms. Additionally, it doubles as an electrocardiogram (ECG) signal amplifier for medical diagnostics. This project illustrates the versatility of op-amp circuits in signal generation and amplification.
This MCC based MPLAB X IDE example shows how to use the Analog Signal Conditioning (OPAMP) peripheral to implement a constant-current driver using just one external resistor. The constant current amperage setting can be adjusted using firmware control.
This project demonstrates the internal gain ladder of the OPA module by setting it to output various DC levels that are proportional to the internal resistor ratios.
To learn about operational amplifier or op amp , that is designed with certain characteristics (high input resistance, low output resistance, and a large differential gain) that make it a nearly ideal amplifier and useful building-block in many circuit applications. OP AMP is almost like an ideal amplifier.
A load cell measures the weight using strain gauges. The difference between the length of the load cell at one side of the cell will help in determining the weight that is applied to it. This will change the output impedance. The output impedance is integrated into a Wheatstone bridge where the difference of the output impedance determines and c…
