Overview
The INA326EA/2K5G4 is a precision, low-drift CMOS instrumentation amplifier manufactured by Texas Instruments. It features a single channel with a 3dB bandwidth of 1 kHz and a common-mode rejection ratio (CMRR) of 100 dB. The device operates on a supply voltage range from 2.7 V to 5.5 V, drawing a typical operating current of 2.4 mA. Key electrical specifications include an input bias current of 2 nA and an input offset voltage of 100 µV. It is designed for surface-mount installation and functions within a temperature range of -40°C to +85°C.
Feature Summary
- Precision low-drift CMOS architecture ensures stable performance over time and temperature variations.
- High common-mode rejection ratio maintains signal integrity in noisy environments.
- Low power consumption supports battery-operated and portable applications.
Applications
- EEG signal acquisition hardware in brain-computer interface systems
- Precision sensor signal conditioning
- Medical instrumentation front-ends
Procurement Notes
Verify component status as the INA326EA/2K5G4 is listed as obsolete or end-of-life by the manufacturer. Confirm availability through authorized distributors or secondary markets. Ensure compatibility with existing PCB footprints if replacing active inventory. Check RoHS compliance documentation for specific revision requirements.
Selection Notes
Select this component when high precision and low drift are critical for low-frequency signal amplification. The 1 kHz bandwidth suits applications requiring filtering of higher frequency noise. Consider the 2.7 V to 5.5 V supply range for compatibility with standard logic levels. Evaluate the 2.4 mA current draw against system power budgets.
Part Context
This part belongs to the INA326 series of instrumentation amplifiers from Texas Instruments. It is specifically packaged in an SOIC format suitable for surface mount technology. The 'G4' suffix typically indicates lead-free and environmental compliance standards consistent with Texas Instruments' product naming conventions.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided data. Verify functional equivalence with other precision instrumentation amplifiers if direct replacement is required due to obsolescence.
FAQ
What is the maximum supply voltage for the INA326EA/2K5G4?
The maximum supply voltage is 5.5 V.
Does the INA326EA/2K5G4 support dual-supply operation?
The datasheet specifies a minimum supply voltage of 2.7 V and a maximum of 5.5 V, indicating it can operate within this range, but specific dual-supply configurations should be verified against the full electrical characteristics table.
