Precision Op Amps (<50 MHz)

ST’s performance operational amplifiers offer features ranging from micropower consumption, to zero-drift, rail-to-rail, low-voltage offset, high voltage and low input bias current.  Our strengths are:

  • The 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
  • Guaranteed specified min/max electrical performances

Excellent precision, Rail-to-rail low power op amp

The OA1MPA, OA2MPA, OA4MPA series of single, dual, and quad 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 STMicroelectronics 5 V CMOS technology and offer an excellent speed/power consumption ratio associated with an ultra-low input bias current. These characteristics make the OAxMPA series ideal for sensor interfaces and active filtering for battery-powered applications in the wearable, portable consumer,  medical and industrial segments.
