LT1994IMS8

Overview

The LT1994IMS8 is a precision, low-noise, fully differential input/output amplifier optimized for single-supply operation. It features rail-to-rail output swing and an adjustable output common-mode voltage independent of the input common-mode voltage. The device offers a gain-bandwidth product of 70MHz and a slew rate of 65V/µs. Key electrical specifications include a maximum DC voltage offset of 2mV, an open-loop gain of 100V/mV, and an output current capability of 85mA. It operates on a wide supply voltage range from 2.375V to 12.6V.

Feature Summary

• Fully differential input and output architecture with internal common-mode feedback for accurate phase balance.
• Adjustable output common-mode voltage via external pin, enabling level shifting for ground-referenced signals.
• Rail-to-rail output swing capable of sourcing and sinking up to 85mA of current.
• Low noise performance with 3nV/sqrt(Hz) density and low distortion characteristics.

Applications

• Driving ADC inputs with differential signals
• Level shifting ground-referenced signals for single-supply systems
• Precision signal conditioning in instrumentation

Procurement Notes

Verify the specific suffix IMS8 corresponds to the MSOP-8 package when ordering. Confirm RoHS compliance status through official manufacturer documentation or authorized distributors prior to procurement. Ensure the component meets all environmental operating temperature ranges specified in the datasheet for your application.

Selection Notes

Select this component for applications requiring high-speed differential amplification with precise common-mode control. It is suitable where low noise and low distortion are critical. Consider the 85mA output drive capability for direct ADC driving. Verify that the 70MHz bandwidth and 65V/µs slew rate meet the signal frequency requirements.

Part Context

The LT1994 is part of Analog Devices' family of fully differential amplifiers designed for high-performance data acquisition systems. The IMS8 designation indicates the 8-lead MSOP surface-mount package. This series is engineered to simplify interface between single-ended sources and differential ADCs while maintaining signal integrity.

Replacement Considerations

Consult official Analog Devices substitution guides for verified alternatives. Cross-reference pinouts and electrical parameters such as GBW, slew rate, and package dimensions before considering any substitute components.
