LT1127CSW#TRPBF

Instrumentation, Op Amps, Buffer Amps Overview

The LT1127CSW#TRPBF is a quad decompensated low noise, high speed precision operational amplifier manufactured by Analog Devices Inc. It operates within a supply voltage range of ±8V to ±22V and functions across an operating temperature range of -40°C to +85°C. The device features a typical gain-bandwidth product of 65MHz and a slew rate of 11V/µs. Input offset voltage is typically 30µV with a maximum of 140µV for the C grade. Supply current per amplifier is 2.6mA typical. The component is housed in a 16-lead SOIC wide package.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific ordering suffix #TRPBF indicates tape and reel packaging and lead-free compliance. Confirm the 'C' grade designation matches the required offset voltage and drift specifications for your application. Ensure the 16-lead SOIC wide footprint aligns with your PCB layout constraints. Check for obsolescence notices as this series may have successor components.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when high bandwidth and low noise are required simultaneously without sacrificing DC precision. The decompensated design offers superior AC performance compared to unity-gain stable counterparts like the LT1125. Ensure the closed-loop gain is set to 10 or greater to maintain stability. Consider the thermal characteristics of the SOIC package for power dissipation calculations.

Instrumentation, Op Amps, Buffer Amps Part Context

The LT1127 is part of the LT1126/LT1127 family of high-performance decompensated op amps. It serves as the quad-channel counterpart to the dual-channel LT1126. Both devices offer enhanced AC performance over the LT1124/LT1125 series while maintaining similar DC specifications. The family is designed for applications requiring high speed and precision in surface-mounted systems.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

LT1127CSW is the non-tape/reel equivalent. LT1125CSW is a unity-gain stable alternative with lower bandwidth.
