INA293A5IDBVT

Overview

The INA293A5IDBVT is a high-voltage, unidirectional current sense amplifier manufactured by Texas Instruments. It operates with a common-mode voltage range from -4 V to 110 V and features a bandwidth of 1.3 MHz. The device provides a fixed gain of 500 V/V and maintains an ultra-precise performance with a maximum input offset voltage of 8 µV and a gain error of 0.02%. It functions within a supply voltage range of 2.7 V to 20 V, consuming 1.5 mA of operating current. The component is housed in a 5-pin SOT-23 package and supports operation temperatures from -40°C to +125°C.

Feature Summary

• Supports high common-mode voltages up to 110 V for flexible system integration
• Delivers ultra-precision accuracy with minimal gain error and low input offset voltage
• Provides high bandwidth for fast transient response in dynamic sensing applications

Applications

• Industrial motor control systems
• Power supply monitoring circuits
• Battery management systems

Procurement Notes

Verify the specific suffix IDBVT indicates tape-and-reel packaging when sourcing. Confirm the A5 variant corresponds to the 500 V/V gain setting required for your design. Ensure the manufacturer is Texas Instruments to guarantee specified electrical characteristics and reliability standards are met.

Selection Notes

Select this component when high common-mode voltage tolerance and precision are critical. The 500 V/V gain suits applications requiring measurement of small currents across large voltage drops. Consider the SOT-23 package constraints for thermal management and board space limitations compared to larger packages.

Part Context

This part belongs to the INA293 family of current sense amplifiers designed for high-voltage environments. It complements other variants like the INA293A4 which offers different gain settings. The series targets industrial and automotive applications requiring robust signal integrity under harsh electrical conditions.

Replacement Considerations

Compatible substitutes include INA293A5IDBVR for reel-to-reel processing or INA293B5IDBVR for alternative grade specifications. Verify pin compatibility and gain accuracy before substitution.
