INA293A3IDBVT

Overview

The INA293A3IDBVT is a unidirectional current sense amplifier from Texas Instruments, housed in a SOT-23-5 package. It features a fixed gain of 100 V/V and supports a common-mode voltage range of -4 V to 110 V. The device offers a bandwidth of 1 MHz, an input offset voltage of 10 µV, and a supply current of 1.5 mA. Operating temperatures range from -40°C to +125°C with a supply voltage span of 2.7 V to 20 V.

Feature Summary

• Provides high precision measurement capabilities through ultra-low input offset voltage specifications.
• Supports high common-mode voltages up to 110 V for flexible system integration.
• Features a wide bandwidth suitable for dynamic current monitoring applications.

Applications

• Automotive battery management systems
• Industrial motor control circuits
• Power supply current monitoring

Procurement Notes

Verify the specific suffix IDBVT indicates the tape-and-reel packaging variant when sourcing components. Confirm that the A3 designation corresponds to the required 100 V/V gain setting for your circuit design. Ensure compatibility with the specified operating temperature range and voltage limits during procurement planning.

Selection Notes

Select this component when a fixed 100 V/V gain is required for unidirectional sensing. The SOT-23-5 package is ideal for space-constrained designs. Consider the 1 MHz bandwidth and low offset voltage for applications demanding accurate dynamic response and minimal DC error.

Part Context

This part belongs to the INA293 family of ultra-precise current sense amplifiers. It shares architectural similarities with other members like the INA293A4IDBVT but differs in its fixed gain configuration. The family is designed for high-voltage, high-bandwidth sensing in automotive and industrial environments.

Replacement Considerations

The INA293A4IDBVT serves as a functional alternative within the same series, offering a different fixed gain of 200 V/V while maintaining similar electrical characteristics and package type.
