Understand the difference.
Compare the meaning, drawing context and source references of two entries. A similar graphic or shared abbreviation does not establish equivalence.
OP-AMP
SymbolsOperational amplifier
An analogue amplifier represented by inverting and non-inverting inputs, an output and its supply connections.
- Drawing use
- Schematic
- Application
- Logic & signals
- Reference family
- Manufacturer
A distinction that matters
An op amp is designed for its documented amplifier behaviour; it is not interchangeable with a dedicated fast voltage comparator.
COMP
SymbolsVoltage comparator
Compares two analogue input voltages and produces the documented output-state indication.
- Drawing use
- Schematic
- Application
- Logic & signals
- Reference family
- Manufacturer
A distinction that matters
A comparator output conveys a comparison result; an op amp operated without feedback is not universally an appropriate substitute.
