INA117KU/2K5G4

Overview

The INA117KU/2K5G4 is a single-channel differential amplifier from Texas Instruments, housed in an SOIC-8 surface-mount package. It operates within a supply voltage range of 10 V to 36 V and draws 1.5 mA of operating current. Key electrical specifications include a gain bandwidth product of 200 kHz, a slew rate of 2.6 V/us, and a common-mode rejection ratio of 70 dB. The device features an input offset voltage of 600 uV and provides an output current capability of 20 mA per channel. It functions reliably across a temperature range of -40 C to +85 C.

Feature Summary

• Provides high common-mode voltage handling capabilities for signal conditioning applications.
• Delivers precise differential amplification with low gain error characteristics.
• Operates efficiently with low power consumption suitable for battery-powered systems.

Applications

• Industrial process control sensor interfaces
• Medical equipment signal processing
• Data acquisition systems

Procurement Notes

Verify the specific suffix G4 indicates lead-free compliance when sourcing. Confirm the /2K5 designation corresponds to cut tape or reel packaging requirements for your assembly line. Ensure the SOIC-8 footprint matches your PCB layout constraints. Check humidity sensitivity levels for proper storage and reflow soldering profiles according to manufacturer guidelines.

Selection Notes

Select this component when high common-mode voltage rejection is required alongside moderate bandwidth. Compare against instrumentation amplifiers if higher CMRR is needed, noting this part offers simpler topology. Evaluate power supply constraints as it requires a minimum of 10 V. Consider the SOIC-8 package size relative to available board space and thermal dissipation needs.

Part Context

This part belongs to the INA117 series of precision differential amplifiers designed by Texas Instruments. It serves as a robust solution for isolating and amplifying signals in noisy environments. The family is known for balancing performance with cost-effectiveness in industrial and medical sectors.

Replacement Considerations

INA117KU is the tube-packaged equivalent without the /2K5 suffix. Verify pin compatibility before substituting other differential amplifiers.
