Description and Introduction

Low Voltage Micropower Quad Operational Amplifier The **OP490EY** is a precision quad operational amplifier designed for high-performance applications requiring low power consumption and excellent accuracy. This component is part of a family of amplifiers known for their low offset voltage, low input bias current, and high common-mode rejection ratio (CMRR), making them ideal for instrumentation, signal conditioning, and data acquisition systems.  

Featuring a wide supply voltage range and rail-to-rail output swing, the OP490EY ensures reliable operation in both single and dual-supply configurations. Its low quiescent current makes it suitable for battery-powered devices, while its robust design minimizes performance degradation over temperature variations.  

Engineers often choose the OP490EY for applications demanding precision and stability, such as medical instrumentation, industrial control systems, and sensor interfaces. The quad configuration allows for space-efficient designs, reducing board footprint while maintaining signal integrity.  

With a combination of low noise, high gain, and thermal stability, the OP490EY provides a dependable solution for analog signal processing. Its compatibility with standard operational amplifier circuits ensures seamless integration into existing designs, making it a versatile choice for both prototyping and production environments.  

For detailed specifications, refer to the manufacturer’s datasheet to ensure optimal performance in your application.

Application Scenarios & Design Considerations

Low Voltage Micropower Quad Operational Amplifier

Alternative Part Number

  • LT1078CN8 --: Dual micropower precision op amp with similar low input offset voltage and low supply current, pin-compatible in 8-pin DIP and a common drop-in for OP490-type dual op amps.
  • TLC27M2CP --: Low-power dual CMOS op amp with low offset voltage and wide supply range, suitable functional replacement for the OP490 in battery-powered precision circuits.
  • MC1458P --: Widely available dual general-purpose op amp in 8-pin DIP with similar pinout and supply range, usable as a lower-cost substitute where precision requirements are relaxed.
