Overview
The INA148UA/2K5 is a precision, single-channel difference amplifier manufactured by Texas Instruments. It features a high common-mode voltage capability of ±200V, allowing accurate signal processing in harsh electrical environments. The device operates within a supply voltage range of 3V to 36V and supports a wide operating temperature range from -40°C to +85°C. Packaged in an 8-SOIC surface-mount case, it integrates a fixed gain configuration for simplified circuit design.
Feature Summary
- Provides precise differential amplification with high common-mode voltage rejection
- Operates reliably across a wide industrial temperature range
- Supports low-voltage single-supply operation
Applications
- High voltage current sensing in motor drives
- Industrial process control signal conditioning
- Data acquisition systems requiring isolated input stages
Procurement Notes
Verify the specific suffix /2K5 indicates tape-and-reel packaging when ordering. Confirm RoHS compliance status matches current manufacturing standards. Ensure the supplier provides original manufacturer documentation to validate authenticity. Check for any recent product change notices regarding pinout or electrical specifications before finalizing procurement.
Selection Notes
Select this component when applications require handling large common-mode voltages without external isolation transformers. It is suitable for designs needing a fixed-gain solution to minimize external component count. Consider the SOIC package constraints for PCB layout and thermal management requirements in dense assemblies.
Part Context
This part belongs to the Texas Instruments difference amplifier family, designed for robust performance in noisy industrial settings. It complements other instrumentation amplifiers by offering higher common-mode voltage tolerance. The UA variant denotes the standard commercial/industrial temperature grade version.
Replacement Considerations
Direct substitutes include the INA148U (tube packaging) for equivalent electrical performance. Verify compatibility with existing board space and pin configurations when swapping between packaging types.
