Key Features

  • Quad channel voltage-feedback op-amp with ultra-low bias current of 0.02 µA for minimal input loading
  • High common-mode rejection ratio of 124 dB (min 100 dB) for superior noise immunity
  • CMOS architecture enabling low quiescent current — ideal for battery-powered and portable designs
  • Small Outline Package (SOIC) with Pb-free compliance for modern PCB integration
  • Wide operating range suitable for precision signal conditioning and instrumentation applications

Applications

The OPA4241UA is well-suited for precision analog signal conditioning in portable and battery-operated instruments where low power consumption is critical. Its high CMRR and ultra-low bias current make it ideal for sensor interface circuits, data acquisition front-ends, and medical instrumentation. The quad-channel configuration also enables compact multi-channel amplifier designs in audio processing and industrial control systems.

Frequently Asked Questions

What is the typical bias current of the OPA4241UA?

The OPA4241UA has a typical bias current (IIB) of 0.02 µA at 25°C with a maximum of 0.025 µA. This ultra-low bias current makes it ideal for high-impedance sensor interfaces and precision measurement applications where minimal input loading is required.

What are the typical applications for the OPA4241UA?

The OPA4241UA is commonly used in battery-powered portable instruments, precision signal conditioning circuits, data acquisition systems, sensor amplification, and medical devices. Its quad-channel design and CMOS architecture make it excellent for multi-channel low-power analog front-end designs.

What package does the OPA4241UA come in?

The OPA4241UA is available in a Small Outline (SOIC) package, which is a surface-mount package well-suited for space-constrained PCB designs. It is Pb-free (RoHS compliant) and supports standard reflow soldering processes.

How does the OPA4241UA compare to single or dual op-amp alternatives?

The OPA4241UA integrates four op-amp channels in a single package, reducing board space and component count compared to using multiple single or dual op-amps. Each channel maintains the same high-performance specs including 100 dB CMRR and 0.02 µA bias current, making it a cost-effective and compact solution for multi-channel designs.
