INA2126UA

Overview

The INA2126UA is a micropower instrumentation amplifier from Texas Instruments, featuring two channels in a 16-pin SOIC surface-mount package. It operates on a single supply voltage ranging from 2.7 V to 36 V or dual supplies of ±1.35 V to ±18 V. Key electrical parameters include a 200 kHz bandwidth, 0.4 V/µs slew rate, and 83 dB common-mode rejection ratio (CMRR). The device draws 175 µA of supply current per channel and offers an input bias current of 10 nA with an input offset voltage of 150 µV.

Feature Summary

• Micropower consumption suitable for battery-operated applications
• High precision performance with low input offset voltage
• Wide single-supply operating range compatible with standard logic levels

Applications

• Portable medical equipment requiring low power consumption
• Industrial process control signal conditioning
• Data acquisition systems with high impedance sources

Procurement Notes

Verify the specific suffix 'UA' corresponds to the 16-SOIC package variant when ordering. Confirm RoHS compliance status as manufacturing processes may update component specifications over time. Ensure the selected distributor provides genuine Texas Instruments products to avoid counterfeit components affecting circuit reliability.

Selection Notes

Select this model for designs requiring a balance between low power usage and moderate bandwidth. Compare against the INA2126E variant if a smaller SSOP package is preferred for space-constrained layouts. Consider the INA2126PA for through-hole mounting requirements in prototyping environments.

Part Context

Part of the INA2126 family of micropower instrumentation amplifiers designed for general-purpose analog signal conditioning. The UA suffix specifically denotes the plastic small-outline integrated circuit (SOIC) package configuration, distinguishing it from other package options within the same functional series.
