Product type
Operational Amplifier ICs, commonly known as op-amps, are integrated circuits that amplify voltage signals. They are made of semiconductor materials and typically consist of multiple transistors, resistors, and capacitors configured to perform various analog functions. Op-amps are essential components in analog electronics, used for signal conditioning, filtering, and mathematical operations such as addition, subtraction, integration, and differentiation.
| Supply Voltage Range | ±1.5V to ±18V |
| Gain Bandwidth Product | 1 MHz to 100 MHz |
| Input Impedance | 100 kΩ to 10 MΩ |
| Output Impedance | 75 Ω to 600 Ω |
| Common Mode Rejection Ratio (CMRR) | 70 dB to 120 dB |
| Operating Temperature Range | -40°C to +125°C |
When selecting an operational amplifier IC, consider the specific application requirements such as supply voltage, bandwidth, and input/output impedance. It's also important to specify the desired gain characteristics and any necessary certifications for your application, such as automotive or medical standards. Quantities can vary based on project needs, so be prepared to discuss your expected volume with suppliers.

The gain can vary widely, but many op-amps provide a voltage gain of 100,000 or more.
Op-amps are primarily analog devices, but they can interface with digital circuits for signal processing.
A single op-amp contains one amplifier, while a dual op-amp contains two amplifiers in one package.
Consider factors like bandwidth, input/output impedance, and power supply requirements.
Yes, operational amplifiers can have performance variations based on temperature, so check the operating temperature range.
Common packages include DIP, SOIC, and TSSOP, depending on the application and space constraints.
