LT1990IMS8-10#PBF

Instrumentation, Op Amps, Buffer Amps Overview

The LT1990IMS8-10#PBF is a micropower precision difference amplifier with a fixed gain of 10 and a 100kHz bandwidth. It operates on supplies ranging from 2.7V to 36V, supporting split ±15V or single 3V/5V configurations. The device features a high common mode input voltage range of ±250V at ±15V supply and up to 85V in single-supply modes. Inputs are fault protected against transients up to ±350V common mode and ±500V differential. It draws less than 180µA supply current and provides rail-to-rail output swing.

Instrumentation, Op Amps, Buffer Amps Feature Summary

• Integrates precision thin-film resistors for a factory-trimmed gain of 10
• Supports extreme common mode voltages up to ±250V via internal division
• Includes robust input protection against high voltage transients
• Delivers rail-to-rail output capability for maximum dynamic range

Instrumentation, Op Amps, Buffer Amps Applications

• High side and low side current monitoring
• Battery cell voltage monitoring
• Signal acquisition in noisy environments
• Fault protected front ends and level sensing

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix IMS8 corresponds to the 8-lead plastic MSOP package variant when sourcing. Confirm the temperature grade matches industrial requirements (-40°C to 85°C). Ensure the ordering part number includes the #PBF designation for lead-free finish compliance. Cross-reference the manufacturer's latest documentation for any potential pin FMEA compatibility updates regarding the MSOP footprint.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when a fixed gain of 10 is required alongside high common mode rejection. It is suitable for applications needing isolation between high voltage inputs and low voltage processing circuits. Consider the 100kHz bandwidth limit for signal frequency requirements. Evaluate the 180µA supply current against power constraints in battery-operated systems.

Instrumentation, Op Amps, Buffer Amps Part Context

This part belongs to the LT1990 family of difference amplifiers designed for high-voltage sensing. While other variants offer selectable gains or different packages, this specific model fixes the gain at 10 and utilizes the MSOP form factor. It complements the broader portfolio by providing a specialized solution for precise differential measurement in electrically noisy or high-potential environments.
