INA126U

Overview

The INA126U is a micropower instrumentation amplifier manufactured by Texas Instruments, housed in an 8-SOIC surface-mount package. It operates on a single supply voltage ranging from 2.7 V to 36 V with a typical supply current of 175 µA. Key electrical specifications include a gain bandwidth product of 200 kHz, a slew rate of 0.4 V/µs, and an input bias current of 10 nA. The device features a maximum input offset voltage of 100 µV and can deliver up to 10 mA of output current. It is rated for operation within a temperature range of -40°C to 85°C.

Feature Summary

Micropower consumption suitable for battery-operated applications
High input impedance with low input bias current
Single-supply operation capability
Low input offset voltage for precision measurements

Applications

Battery-powered medical instrumentation
Strain gauge and load cell interfaces
Thermocouple amplification
Photodiode preamplifiers

Procurement Notes

Verify the specific suffix 'U' indicates the 8-SOIC package variant when ordering. Confirm RoHS compliance status as per the latest manufacturer documentation. Ensure the operating environment remains within the specified -40°C to 85°C temperature range. Check for any recent Product Change Notifications (PCN) regarding assembly or material changes that may affect long-term sourcing stability.

Selection Notes

Select the INA126U when low power consumption is critical alongside moderate precision requirements. Compare against higher-speed variants if bandwidth exceeds 200 kHz is needed. Consider the 8-SOIC package constraints for PCB layout. Evaluate if the 100 µV max offset voltage meets the system's accuracy needs without external trimming.

Part Context

The INA126 belongs to Texas Instruments' family of micropower instrumentation amplifiers designed for general-purpose signal conditioning. It offers a cost-effective solution for applications requiring low power and single-supply operation. The U suffix specifically denotes the plastic small-outline package, distinguishing it from other form factors like the dual-channel INA2126 or high-performance INA128.
