INA126E/250

Overview

The INA126E/250 is a micropower instrumentation amplifier manufactured by Texas Instruments. It features a single circuit configuration housed in an 8-VSSOP surface-mount package. Key electrical specifications include a supply voltage range of 2.7 V to 36 V, a -3 dB bandwidth of 200 kHz, and a slew rate of 0.4 V/µs. The device draws 175 µA of supply current with an input bias current of 25 nA and an input offset voltage of 250 µV. It operates within a temperature range of -55°C to +125°C.

Feature Summary

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

Applications

• Strain gauge measurements
• Thermocouple amplification
• Medical instrumentation signal conditioning

Procurement Notes

Verify the specific suffix 'E/250' against the manufacturer's official datasheet to confirm the tape-and-reel packaging quantity and RoHS compliance status. Ensure the ordering part number matches the required package type and temperature grade before finalizing procurement orders.

Selection Notes

Select this component when low power consumption is critical alongside moderate precision requirements. The wide supply voltage range allows flexibility in system design. Verify that the 200 kHz bandwidth meets the signal frequency needs and that the 8-VSSOP package fits the PCB layout constraints.

Part Context

This part belongs to the INA126 family of micropower instrumentation amplifiers from Texas Instruments. The family offers a balance of performance and power efficiency, designed for general-purpose analog signal conditioning tasks where low quiescent current is a primary design constraint.

Replacement Considerations

Check for direct pin-compatible alternatives such as the INA128 or INA333 if higher precision or different packaging options are required. Confirm that substitute devices meet the same supply voltage and temperature range specifications.
