Overview
The INA2126EA/2K5 is a micropower instrumentation amplifier from Texas Instruments, featuring two channels in an SSOP-16 surface-mount package. It operates on a supply voltage range of 2.7 V to 36 V with a maximum operating supply current of 175 uA. Key electrical specifications include a gain-bandwidth product of 200 kHz, a common-mode rejection ratio of 83 dB, and an input bias current of 25 nA. The device exhibits an input offset voltage of 50 uV and supports gains ranging from 5 V/V to 10,000 V/V. It functions within a temperature range of -40°C to +85°C.
Feature Summary
- Micropower operation suitable for battery-powered applications
- High common-mode rejection ratio for accurate signal conditioning
- Wide single-supply voltage capability
- Adjustable gain range from 5 V/V to 10,000 V/V
Applications
- Battery-powered sensor interfaces
- Medical instrumentation
- Industrial process control systems
- Strain gauge amplification
Procurement Notes
Verify the specific suffix 'EA/2K5' against the manufacturer's official datasheet to confirm the exact package type (SSOP-16) and reel quantity specifications. Ensure compatibility with the required operating temperature range and supply voltage constraints before procurement. Cross-reference the part number with authorized distributors to confirm authenticity and traceability.
Selection Notes
Select this component when low power consumption is critical alongside moderate bandwidth requirements. The 200 kHz gain-bandwidth product and 175 uA supply current make it suitable for precision applications where energy efficiency is prioritized over high-speed performance. Consider the 83 dB CMRR for environments with significant common-mode noise.
Part Context
The INA2126 belongs to Texas Instruments' family of micropower instrumentation amplifiers, offering both single and dual versions. This series is designed for general-purpose precision applications requiring low power and high accuracy. The EA variant specifically denotes the SSOP-16 surface-mount packaging option, distinguishing it from other package styles within the same functional family.
Replacement Considerations
Consult the official datasheet for direct pin-compatible alternatives within the INA2126 family or comparable micropower instrumentation amplifiers from other manufacturers. Verify that any substitute matches the 2.7 V to 36 V supply range and SSOP-16 footprint.
