Overview
The INA2126E/250 is a dual-channel micropower instrumentation amplifier manufactured by Texas Instruments. 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. The device features a gain-bandwidth product of 200 kHz and a typical slew rate of 0.4 V/us. Key electrical specifications include a maximum input offset voltage of 250 µV, a minimum common-mode rejection ratio of 83 dB, and an operating supply current of 175 µA per channel. It is housed in a 16-pin SSOP package.
Feature Summary
- Micropower consumption with 175 µA supply current per channel for battery-operated applications
- High precision performance with low input offset voltage and high common-mode rejection ratio
- Wide single-supply operation capability from 2.7 V to 36 V
Applications
- Battery-powered measurement systems
- Industrial process control signal conditioning
- Medical instrumentation front-ends
Procurement Notes
Verify the specific suffix /250 indicates the standard tube packaging configuration as distinct from tape-and-reel variants like /2K5. Confirm the package type is SSOP-16 and check RoHS compliance status against the latest manufacturer documentation before ordering.
Selection Notes
Select this component when a dual-channel instrumentation amplifier is required with low power consumption and moderate bandwidth. Ensure the application voltage range fits within the 2.7 V to 36 V limit and that the 200 kHz bandwidth meets the signal frequency requirements.
Part Context
This part belongs to the INA2126 family of micropower instrumentation amplifiers from Texas Instruments. The family includes single-channel (INA2125) and dual-channel (INA2126) versions available in various packages such as SOIC, SSOP, and PDIP. The /250 suffix typically denotes the standard tube packaging format.
Replacement Considerations
Direct substitutes within the same family include INA2126EA/250 and INA2126UG4. Verify pinout compatibility and package dimensions (SSOP-16) when replacing.
