INA2133UAE4

Overview

The INA2133UAE4 is a dual-channel high-speed precision differential amplifier manufactured by Texas Instruments. It operates within a supply voltage range of 4.5 V to 36 V and consumes 950 uA of operating supply current. The device features a gain-bandwidth product of 1.5 MHz and a slew rate of 4.5 V/us. Key electrical specifications include an input offset voltage of 450 uV, a common-mode rejection ratio of 80 dB, and operation across a temperature range from -55 C to +125 C. It is housed in a SOIC-14 surface-mount package.

Feature Summary

• Dual-channel architecture for simultaneous signal processing
• High-speed performance with defined bandwidth and slew rate capabilities
• Precision design characterized by low input offset voltage
• Extended industrial temperature rating for harsh environments

Applications

• Industrial process control systems requiring differential signal conditioning
• Medical instrumentation utilizing precision analog front ends
• Data acquisition systems demanding high common-mode rejection
• Test and measurement equipment needing wide dynamic range amplification

Procurement Notes

Verify the specific suffix 'E4' against the manufacturer's latest documentation to confirm lead-free status and RoHS compliance requirements. Ensure the SOIC-14 package dimensions match your PCB footprint constraints. Confirm that the specified operating temperature range meets your environmental design criteria before finalizing procurement decisions.

Selection Notes

Select this component when dual-channel differential amplification is required alongside high-speed signal integrity. The 80 dB CMRR makes it suitable for noisy industrial environments. Compare the 450 uV offset voltage against stricter precision requirements; if lower offset is needed, consider other series members. Verify power supply compatibility with the 4.5 V minimum threshold.

Part Context

This part belongs to the INA2133 family of differential amplifiers designed for high-performance applications. It serves as a dual-channel variant within Texas Instruments' portfolio of precision analog components. The device complements single-channel solutions where space efficiency and channel matching are critical for balanced signal paths in complex electronic systems.
