Overview
The INA133UA/2K5 is a high-speed precision differential amplifier manufactured by Texas Instruments. It features a single channel with a -3dB bandwidth of 1.5MHz and a slew rate of 5V/μs. The device operates on a single supply voltage ranging from 4.5V to 36V, or dual supplies of ±2.25V to ±18V. Key electrical specifications include a maximum offset voltage of 900μV and a supply current of approximately 950μA. It is housed in an 8-SOIC package.
Feature Summary
- High-speed operation with 1.5MHz bandwidth for precise signal processing
- Single-supply compatibility supporting wide voltage ranges up to 36V
- Precision performance with low offset voltage characteristics
Applications
- High-side current shunt monitoring
- Industrial process control signal conditioning
- Medical equipment data acquisition
Procurement Notes
Verify the specific suffix /2K5 indicates tape-and-reel packaging when ordering. Confirm the manufacturer is Texas Instruments to ensure authenticity. Check the datasheet for the latest thermal and electrical limits before integration. Ensure the 8-SOIC footprint matches the design layout requirements.
Selection Notes
Select this component when a single-supply differential amplifier with moderate speed is required. The 1.5MHz bandwidth suits applications needing faster response than standard instrumentation amplifiers but lower speed than high-frequency op-amps. Consider the 900μV offset if high DC accuracy is critical for the application.
Part Context
This part belongs to the INA13x family of precision differential amplifiers. It serves as a specialized solution for converting differential signals to single-ended outputs without external resistors. The /2K5 designation specifically denotes the reel quantity and packaging format for automated assembly.
Replacement Considerations
INA133U and INA133UA are direct functional equivalents. Verify that the non-suffix versions meet the same packaging and reel requirements if transitioning from bulk to tape-and-reel formats.
