LT1881CS8#PBF

Instrumentation, Op Amps, Buffer Amps Overview

The LT1881CS8#PBF is a dual precision operational amplifier featuring rail-to-rail output swing and picoampere input bias currents. It operates on supply voltages ranging from 2.7V to 36V, with full specification between 5V and ±15V. The device offers an offset voltage of up to 80μV and drift of 0.8μV/°C. Key electrical parameters include a gain-bandwidth product of 1MHz, slew rate of 0.35V/µs, and supply current of 0.65mA per amplifier at 5V. It maintains stability in unity-gain configurations driving capacitive loads up to 1000pF.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix #PBF indicates lead-free finish and RoHS compliance when sourcing. Confirm the CS8 package variant matches the required surface mount footprint. Ensure the industrial temperature grade aligns with the intended operating environment constraints. Cross-reference the manufacturer part number against authorized distributor catalogs to ensure authenticity.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when ultra-low input bias current is critical alongside rail-to-rail output requirements. Consider the LT1884 or LT1885 if higher speed is needed, accepting slightly reduced capacitive load drive. Evaluate the LT1881A grade if tighter offset voltage specifications below 50μV are mandatory for the application design.

Instrumentation, Op Amps, Buffer Amps Part Context

This device belongs to the LT1881/LT1882 family of dual and quad precision op amps. It shares architectural similarities with the LT1884/LT1885 series but prioritizes input bias current performance and capacitive load driving capability over bandwidth. The S8 package provides a compact solution for space-constrained precision analog signal conditioning circuits.

Instrumentation, Op Amps, Buffer Amps FAQ

Does exceeding the input common mode range cause phase reversal?

No, exceeding the common mode range causes the gain to drop to zero, but no phase reversal will occur.

How should input resistances be balanced for optimal performance?

Input resistances should not be balanced; keeping impedance at either input as small as possible minimizes total circuit error due to uncorrelated bias currents.
