Operational Amplifiers (Op Amps)

ST’s op amp portfolio provides a unique choice of high performance, low power, precision op amps and tiny packages.

  • Largest  micropower op amp portfolio on the market, with consumption as low as 2 µA
  • Reliable high volume supplier of both standard and high-performance op amps
  • Space-saving packages, such as DFN, QFN, SOT-23 and SC-70

ST’s precision op amp solutions include zero drift amplifiers and amplifiers with a low offset drift over temperature. Thus the precision op amps from ST are a perfect fit for use with any sensor, including gas, temperature, pressure, and position sensors.

ST’s low-power operational amplifier solutions include widely used devices, but also provide design engineers with upgrade options such as better accuracy, a standby feature and small packages. 

Our automotive-grade products are AEC-Q100 qualified and tested with certified high-reliability flow, to meet the very specific, rigorous demands of the automotive market.

Free samples are available for some of our op amps. Find the one for your application and give it a try!

TSV7 series: excellent precision (200 µV), low-power (10 µA or 60 µA) op amp

The TSV711, TSV712, TSV714, TSV731, TSV732, TSV734 series of single-, dual-, and quad-channel operational amplifiers offers low-voltage operation (1.5 to 5.5 V), rail-to-rail inputs and outputs, and an excellent accuracy (VIO lower than 200 μV at 25 °C). Housed in the smallest industrial packages, these low-power devices benefit from ST’s 5 V CMOS technology and offer an excellent speed/power consumption ratio associated with an ultra-low input bias current. These characteristics make the TSV7 series ideal for sensor interfaces and active filtering for battery-powered applications in the wearable, portable consumer, medical and industrial segments.

TSX711: High-precision low-power 16 V CMOS op amps

The TSX711 offers low power consumption and exhibits an offset voltage less than 200 µV. Its rail-to-rail input and output functions, associated with an extended power supply range from 2.7 V to 16 V, allows the TSX711 to be used on a wide range of applications. The TSX711 perfectly fits automotive requirements: -40°C to 125°C temperature range and ability to sustain 4 kV ESD. It is available in a tiny SOT-23 package.
