INA126U/2K5G4

Overview

The INA126U/2K5G4 is a micropower instrumentation amplifier manufactured by Texas Instruments. It features a single circuit in an 8-SOIC package. Key electrical parameters include a supply current of 175µA, output current of 10 mA, and a slew rate of 0.4V/µs. The device operates with a voltage span from 2.7 V to 36 V and has a -3dB bandwidth of 200 kHz. Input bias current is 10 nA, and input offset voltage is 100 µV. The operating temperature range is -40°C to 85°C.

Feature Summary

• Micropower consumption suitable for battery-operated applications
• Low input bias current for high-impedance source interfacing
• Wide single-supply voltage operation capability

Applications

• Battery-powered sensor signal conditioning
• Medical instrumentation front ends
• Industrial process control systems

Procurement Notes

Verify the specific suffix 'G4' against the manufacturer's latest documentation to confirm RoHS compliance status and lead time requirements. Ensure the ordering part number matches the exact package and tape-and-reel specifications required for your assembly process. Cross-reference the datasheet revision date to validate all electrical characteristics before finalizing procurement.

Selection Notes

Select this component when low power consumption is critical alongside moderate precision requirements. The 175µA supply current makes it suitable for portable devices. Compare input offset voltage and bias current specifications against other INA126 variants if higher precision or wider temperature ranges are needed for the specific application environment.

Part Context

This part belongs to the INA126 family of micropower instrumentation amplifiers. It shares core architectural similarities with other members like the INA126E and INA126UA but differs in packaging and specific suffix designations. The U variant indicates surface-mount SOIC packaging, while the /2K5 denotes reel quantity specifications.
