INA2126P

Overview

The INA2126P is a dual micropower instrumentation amplifier from Texas Instruments, housed in a 16-pin PDIP package. It operates on single or dual supplies ranging from 2.7 V to 36 V. Key electrical parameters include a gain bandwidth product of 200 kHz and a maximum input offset voltage of 0.5 mV. The device features a minimum common-mode rejection ratio of 74 dB and a maximum supply current of 0.4 mA per channel. It supports a wide operating temperature range from -40°C to +85°C.

Feature Summary

• Micropower consumption for extended battery life
• High precision with low input offset voltage
• Wide single or dual supply voltage operation

Applications

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

Procurement Notes

Verify the specific suffix against official datasheets to confirm pinout and performance grades. Ensure the PDIP package matches your PCB footprint requirements. Confirm RoHS compliance status for regulatory adherence. Cross-reference the manufacturer part number with authorized distributor listings to avoid counterfeit components.

Selection Notes

Select this component when low power consumption is critical alongside moderate precision requirements. The dual-channel configuration allows for cost-effective multi-sensor designs. Verify that the 74 dB CMRR meets your noise rejection needs. Consider the PDIP package constraints for high-density board layouts.

Part Context

This part belongs to the INA2126 family of micropower instrumentation amplifiers. It offers a dual-channel solution compared to single-channel variants like the INA2127. The family provides a balance between power efficiency and accuracy for general-purpose analog signal processing applications.
