Overview
The INA126EA/250 is a micropower instrumentation amplifier manufactured by Texas Instruments, housed in an 8-VSSOP 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 150 µV and supports gains from 5 V/V to 10,000 V/V via a single external resistor.
Feature Summary
- Micropower consumption suitable for battery-operated applications
- High common-mode rejection ratio for accurate signal conditioning
- Single-resistor gain setting capability for simplified circuit design
- Low input bias current and low noise characteristics
Applications
- Strain gauge and load cell interfaces
- Medical instrumentation such as ECG and EEG preamplifiers
- Industrial process control sensor signal conditioning
- Photodiode and transimpedance amplifier circuits
Procurement Notes
Verify the specific suffix EA/250 against the manufacturer datasheet to confirm the 8-VSSOP package and temperature range. Ensure compatibility with RoHS3 standards if required by your assembly process. Cross-reference the DigiKey part number INA126EATR-ND or similar distributor codes for accurate ordering details and lead times.
Selection Notes
Select this component when low power consumption is critical alongside high precision requirements. The wide supply voltage range allows flexibility in system design. Consider the 8-VSSOP package size for space-constrained PCB layouts. Verify that the 200 kHz bandwidth meets the frequency response needs of the target application.
Part Context
This part belongs to the INA126 family of micropower instrumentation amplifiers. It shares core architecture with other variants like the INA126E/2K5 but differs in packaging and reel quantity specifications. The family is designed for general-purpose precision applications requiring low power and high accuracy.
Replacement Considerations
Direct substitutes within the same family include INA126E/2K5, though package and tape/reel specifications may differ. Check datasheets for pinout compatibility and parameter variations before substitution.
