Operational amplifiers

In today’s digital world, many signals start as an analog one. Most sensors already have their own analog signal conditioning circuit, but an operational amplifier is still a key device when you need more complex amplification and filtering, or just for interfacing analog signals with an ADC or a microcontroller.    

Why you should choose ST Op Amps

ST's operational amplifier portfolio provides a unique choice of high performance, low power, precision op amps and tiny packages. It addresses voltages from 1.5 V to 44 V and operating temperatures from -40 to 150 °C. The automotive-grade op-amp portfolio features extreme reliability and quality demanded by automotive applications.

• Largest micropower Op Amp portfolio on the market, with consumption as low as 600 nA
• High volume supplier of highly reliable standard and high-performance op amps
• Space-saving packages, such as CSP, DFN, QFN, SOT-23 and SC-70
• Continuously increasing list of high-performance Op Amps with a 10-year longevity commitment

How do I pick the right Op Amp for an application?

Even though some may consider op amps as a commodity, they are not. Modern high-performance devices have a wide range of variable parameters. One device can have almost ideal parameters, while another may be little worse, and others can be completely different. The main key performance indicators for operational amplifiers can be listed as following:
