INA2126E/250G4

Overview

The INA2126E/250G4 is a micropower instrumentation amplifier manufactured by Texas Instruments. It features a gain bandwidth product of 200 kHz and a slew rate of 0.4 V/us. The device operates on a single or dual power supply ranging from 2.7V to 36V, with a maximum supply current of 175 uA per channel. Key electrical specifications include an input offset voltage of 50 µV, an input bias current of 25 nA, and a common mode rejection ratio of 83 dB. It is housed in a 16-SSOP package.

Feature Summary

• Micropower consumption suitable for battery-operated applications
• High precision with low input offset voltage and bias current
• Wide single-supply operating range from 2.7V to 36V

Applications

• Battery-powered measurement systems
• Industrial process control signal conditioning
• Medical equipment sensor interfaces

Procurement Notes

Verify the G4 suffix indicates lead-free compliance and RoHS status. Confirm the SSOP-16 package dimensions match design requirements. Check humidity sensitivity level for storage and reflow soldering profiles. Ensure the 250 µV offset voltage grade meets system accuracy needs.

Selection Notes

Select this component for applications requiring low power consumption alongside moderate precision. The wide supply voltage range simplifies power management in portable devices. Compare input bias current and noise density against other instrumentation amplifiers if high-frequency performance is critical.

Part Context

This part belongs to the INA2126 series of micropower instrumentation amplifiers. The series offers both single and dual channel versions. The E/250 designation specifies the temperature grade and offset voltage binning. The G4 suffix typically denotes environmental compliance attributes.

Replacement Considerations

INA2126EA/250 is a pin-compatible variant with the same electrical characteristics but potentially different packaging or environmental suffixes.
