Operational Amplifiers (Op Amps)

ST has a wide range of operational amplifiers, including both industry-standard and high performance op amps. Our strengths include:

  • 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

Our JFET, BiPolar, CMOS and BiCMOS technologies allow our products to support:

  • A wide supply range, from 1 V to 36 V
  • Flexible input configurations
  • High ratios of performance-to-power consumption

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.

Extremely low power, 5V op amp

The OA1NP, OA2NP, OA4NP series of CMOS op amp provide an industry-leading low power consumption thus enabling high performance and longer operating times, even when supplied by small coin cell batteries. The single, dual and quad amplifiers offer an ultra-low power typical consumption of 580 nA  when powered from a 1.8 V voltage supply. The OAxNP series can be powered off from a voltage source ranging  from 1.5 to 5.5 V and the 8 kHz gain bandwidth of these devices makes them ideal for sensor signal conditioning and battery-supplied applications, such as wearable devices , CO detectors and medical handheld tools.
