Overview
The INA133UG4 is a precision instrumentation amplifier manufactured by Texas Instruments, featuring a single channel in an SOIC-8 package. It operates with a bandwidth of 1.5 MHz and a slew rate of 4.50 V/μs. Key electrical parameters include an input offset voltage of 450 µV, a supply current of 950 µA, and a common-mode rejection ratio of 80 dB. The device supports a maximum supply voltage of 36.0 V and functions within a temperature range of -40°C to 85°C.
Feature Summary
- Provides high-speed signal amplification suitable for dynamic applications
- Delivers precision performance with low input offset voltage characteristics
- Operates efficiently with low quiescent current consumption
Applications
- Industrial process control systems requiring precise signal conditioning
- Medical equipment utilizing differential sensor inputs
- Data acquisition modules interfacing with transducers
Procurement Notes
Verify the specific suffix 'G4' against official manufacturer documentation to confirm compliance with RoHS directives and lead-free manufacturing standards. Ensure the ordering part number matches the exact pinout and package dimensions required for your PCB layout. Cross-reference the datasheet revision history to validate all electrical specifications before finalizing procurement orders.
Selection Notes
Select this component when a balance of moderate precision and higher bandwidth is required compared to standard low-speed instrumentation amplifiers. Consider the 36V maximum supply capability for applications involving higher voltage rails. Evaluate the 80 dB CMRR against system noise requirements to ensure adequate common-mode interference rejection.
Part Context
This device belongs to the INA133 family of instrumentation amplifiers from Texas Instruments. It shares core architectural similarities with other members like the INA133U but differs in specific packaging or environmental qualification details indicated by the suffix. The family is designed for general-purpose analog signal processing tasks.
Replacement Considerations
The INA133U serves as a direct functional equivalent within the same product line. Verify that any substitute maintains compatibility with the SOIC-8 footprint and meets the original design's thermal and electrical constraints.
