ETB-150 – Study of OP-AMP Comparator is a specialized educational trainer designed to demonstrate the functioning of an Operational Amplifier (OP-AMP) used as a Comparator. Comparators are essential in analog electronics for comparing voltage levels and generating digital outputs based on input conditions.
This trainer includes a built-in power supply, test points, and component configurations that allow students to analyze both inverting and non-inverting comparator modes. It enables the observation of output waveforms when the OP-AMP compares different input voltages — a fundamental concept used in analog-to-digital converters, zero-crossing detectors, and Schmitt triggers.
Key Features:
Demonstrates both inverting and non-inverting OP-AMP comparator circuits
Built-in regulated power supply for standalone operation
Clearly marked test points for waveform observation
Facilitates understanding of voltage level detection and threshold comparison
Ideal for analog electronics labs and comparator circuit studies
Uses standard OP-AMP IC like UA741 or equivalent
