INA2133UA/2K5

Overview

The INA2133UA/2K5 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 ranging from 4.5 V to 36 V, drawing an operating supply current of 950 uA. Key electrical specifications include a common mode rejection ratio of 80 dB and an input offset voltage of 450 uV. It supports an extended industrial temperature range from -55 C to +125 C and is housed in a SOIC-14 surface-mount package.

Feature Summary

• High-speed operation with 1.5 MHz gain bandwidth product
• Precision performance with low input offset voltage
• Wide single-supply voltage capability up to 36 V
• Extended industrial temperature rating for harsh environments

Applications

• Industrial process control signal conditioning
• Medical equipment data acquisition systems
• High-speed sensor interface circuits

Procurement Notes

Verify the specific suffix /2K5 indicates tape and reel packaging when ordering. Confirm the SOIC-14 package type matches your PCB footprint requirements. Ensure the component meets the required temperature grade for your application environment. Cross-reference the manufacturer part number with official datasheets to confirm pinout compatibility before integration into final designs.

Selection Notes

Select this component when high-speed differential amplification is required alongside precision accuracy. The wide supply voltage range allows flexibility in power design compared to lower-voltage alternatives. Consider the 80 dB CMRR for noise rejection needs in noisy industrial environments. Evaluate the 950 uA supply current against total system power budgets for efficiency optimization.

Part Context

This device belongs to the INA2133 family of high-speed precision differential amplifiers. It integrates laser-trimmed resistors to provide accurate gain without external components. The series is designed for applications requiring fast response times and high common-mode rejection ratios in compact surface-mount packages.

Replacement Considerations

Check for direct substitutes within the INA2133 family such as INA2133U or INA2133U-EP. Verify that any replacement maintains the same SOIC-14 package and electrical characteristics. Ensure thermal performance and supply voltage limits are compatible with existing circuit designs.
