Low-Power, High-Performance Operational Amplifiers

Our operational amplifiers (op amps) can address virtually any design requirement. From cost-effective general-purpose amplifiers to precision amplifiers that minimize errors resulting from harsh electrical environments, our op amps minimize development risk and increase system performance by providing reliable, well-documented functionality for years to come.

General-Purpose Amplifiers

  • Wide selection of bandwidths, from 9 kHz to 80 MHz, to address a wide variety of applications
  • Extend battery runtime with operating voltages as low as 1.4V and quiescent currents as low as 450 nA
  • Additional electromagnetic filtering on select devices provides extra protection in electrically harsh environments

Precision Amplifiers

  • Maximum input offsets below 250 µV to enable high-accuracy designs
  • Extend battery runtime with operating voltages as low as 1.8V and ultra-low quiescent currents for the given bandwidth
  • A wide operating temperature range of -40°C to +125°C provides a robust solution even at extreme temperatures

Zero-Drift Amplifiers

  • Industry-leading accuracy performance with maximum offsets as low as 2 µV
  • Offset drift as low as 15 nV/°C, which enables accuracy across temperature extremes
  • Additional electromagnetic filtering on select devices provides extra protection in electrically harsh environments

Differential Amplifiers

  • Industry-leading low input offsets of less than 150 µV to enable high-accuracy signal measurement
  • Designed for low distortion and fast settling to maintain signal integrity, even at high speeds
  • Ideal for use with Microchip’s family of high-speed SAR ADCs, the driver allows a system to take advantage of the full performance of the converter across a wide range of operating conditions
