Overview
The INA125U/2K5 is a low-power instrumentation amplifier manufactured by Texas Instruments. It integrates a precision voltage reference and features a single-channel architecture with a gain set by one external resistor. The device operates on supply voltages ranging from 2.7 V to 36 V, drawing a typical quiescent current of 460 µA. It provides a common-mode rejection ratio of 100 dB and a bandwidth of 150 kHz. The component is housed in an 8-pin SOIC package and supports operation across a temperature range of -40°C to +85°C.
Feature Summary
- Integrates a precision voltage reference for simplified circuit design
- Requires only a single external resistor to set the gain
- Provides high common-mode rejection ratio for accurate signal conditioning
Applications
- Strain gauge measurements
- Bridge sensor interfaces
- Medical equipment signal processing
Procurement Notes
Verify the specific suffix '2K5' corresponds to the tape-and-reel packaging configuration as defined in the official datasheet. Confirm that the integrated reference voltage matches system requirements. Ensure the SOIC-8 package dimensions align with the target PCB layout constraints before finalizing procurement orders.
Selection Notes
Select this component when a low-power instrumentation amplifier with an integrated reference is required. It is suitable for applications needing high common-mode rejection and simple gain adjustment via a single resistor. Consider the operating voltage range and thermal performance to ensure compatibility with the intended environment.
Part Context
This part belongs to the INA125 family of instrumentation amplifiers from Texas Instruments. The family is characterized by low power consumption and high accuracy. The 'U' designation indicates the surface-mount SOIC package, while '/2K5' specifies the reel quantity and packaging format for automated assembly processes.
Replacement Considerations
Check for direct pin-compatible alternatives within the same manufacturer's portfolio that offer similar gain settings and reference integration. Verify that any substitute maintains the required common-mode rejection ratio and operating voltage range.
