INA2133U/2K5G4

Overview

The INA2133U/2K5G4 is a high-speed precision differential amplifier manufactured by Texas Instruments. It features two channels with a gain bandwidth product of 1.5 MHz and a slew rate of 4.5 V/us. The device operates on supply voltages between 4.5 V and 36 V, drawing 950 uA of operating current. It provides a common mode rejection ratio of 80 dB and an input offset voltage of 450 uV. Designed for surface mount installation, it is housed in an SOIC-14 package and functions within a temperature range of -55 C to +125 C.

Feature Summary

• High-speed operation with a 1.5 MHz gain bandwidth product and 4.5 V/us slew rate
• Precision performance characterized by low input offset voltage and high common mode rejection
• Wide single-supply voltage capability ranging from 4.5 V to 36 V
• Extended industrial temperature rating suitable for demanding environments

Applications

• Industrial process control signal conditioning
• Medical equipment data acquisition systems
• Test and measurement instrumentation

Procurement Notes

Verify the specific suffix G4 indicates RoHS compliance status during procurement. Confirm the /2K5 packaging designation corresponds to reel quantities as specified by the manufacturer. Ensure the SOIC-14 footprint matches the target PCB layout requirements. Check moisture sensitivity levels for proper storage and handling protocols prior to assembly.

Selection Notes

Select this component when high-speed differential amplification is required alongside wide supply voltage tolerance. The SOIC-14 package offers a balance of thermal performance and board space efficiency. Consider the 450 uV input offset voltage for applications requiring moderate DC accuracy without external trimming. Evaluate the 950 uA supply current against power constraints in battery-operated or thermally sensitive designs.

Part Context

This part belongs to the INA213x series of differential amplifiers from Texas Instruments. It shares architectural similarities with other members like the INA2132 and INA2134 but differs in speed and channel configuration. The series targets applications needing robust signal integrity in noisy industrial environments while maintaining low power consumption relative to higher-performance alternatives.

Replacement Considerations

INA2132U/2K5G4: Lower speed variant with similar pinout. INA2134UA/2K5: Dual-channel audio line receiver with different gain characteristics.
