INA133UA

Overview

The INA133UA is a high-speed, precision difference amplifier manufactured by Texas Instruments. It features a fixed gain of 0.1 V/V and operates with a single supply voltage ranging from 4.5V to 36V. Key electrical specifications include a bandwidth of 1.5 MHz, a slew rate of 4.50 V/μs, and an input offset voltage of 450 µV. The device draws a maximum supply current of 950 µA and offers a common-mode rejection ratio of 80 dB. It is housed in an 8-pin SOIC package and supports an operating temperature range from -40°C to 85°C.

Feature Summary

Fixed internal gain of 0.1 V/V for precise signal attenuation
High-speed performance with 1.5 MHz bandwidth
Precision characteristics with low input offset voltage
Single-supply operation capability

Applications

Signal conditioning for sensor interfaces
Data acquisition systems requiring fixed attenuation
Industrial process control instrumentation
Medical equipment signal processing

Procurement Notes

Verify the specific suffix 'UA' against the manufacturer's latest datasheet to confirm pinout compatibility and package dimensions. Ensure the procurement source provides valid traceability documentation. Confirm that the component meets the required environmental standards for the intended application environment before finalizing orders.

Selection Notes

Select this component when a fixed attenuation factor of 0.1 is required without external resistors. It is suitable for applications needing high speed and precision within a single-supply architecture. Compare bandwidth and offset voltage requirements against alternative difference amplifiers if higher gains or different supply constraints are present.

Part Context

The INA133UA belongs to the Burr-Brown family of difference amplifiers acquired by Texas Instruments. This series is designed for applications requiring accurate differential signal processing with minimal external component count. The UA variant specifically denotes the standard industrial grade version in the SOIC-8 package format.
