INA180A4IDBVT

Overview

The INA180A4IDBVT is a single-channel current sense amplifier from Texas Instruments, housed in a SOT-23-5 package. It operates on a supply voltage ranging from 2.7 V to 5.5 V with a quiescent current of 260 uA. The device features a fixed gain of 200 V/V and supports a common-mode voltage range from -200 mV to 26 V. Key electrical specifications include a gain bandwidth product of 105 kHz, an input offset voltage of 100 uV, and a common-mode rejection ratio of 100 dB. It functions within a temperature range of -40 C to +125 C.

Feature Summary

• Provides high-side current sensing capability with a wide common-mode voltage range extending below ground.
• Delivers precise amplification through a fixed internal gain of 200 V/V for simplified circuit design.
• Ensures signal integrity via a 100 dB common-mode rejection ratio and low input offset voltage.

Applications

• Battery management systems
• Load switch control circuits
• Overcurrent protection designs

Procurement Notes

Verify the specific suffix IDBVT confirms the SOT-23-5 surface-mount package and industrial temperature grade. Confirm the A4 variant designation corresponds to the required 200 V/V fixed gain setting. Ensure compatibility with the target PCB footprint and thermal requirements for the intended operating environment.

Selection Notes

Select this component when a compact SOT-23-5 form factor is required alongside a fixed gain of 200 V/V. It is suitable for applications needing operation up to 26 V common-mode voltage with a maximum supply of 5.5 V. Consider the 260 uA quiescent current for power-sensitive designs requiring industrial temperature stability.

Part Context

This part belongs to the INA180 series of current sense amplifiers designed for low-power, space-constrained applications. The series offers various fixed gain options and packaging styles to accommodate different system requirements while maintaining high accuracy and wide common-mode voltage capabilities.

Replacement Considerations

INA180A2IDBVT (Gain 50 V/V), INA180A3IDBVT (Gain 100 V/V), INA180A5IDBVT (Gain 500 V/V). Verify gain requirements match before substitution.
