INA180B3IDBVT

Overview

The INA180B3IDBVT 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 100 V/V and supports a common-mode voltage range from -200 mV to 26 V. Key electrical specifications include a gain bandwidth product of 150 kHz, input offset voltage of 100 uV, and input bias current of 80 uA. It provides a common-mode rejection ratio of 100 dB and operates within a temperature range of -40 C to +125 C.

Feature Summary

• Supports low-side and high-side current sensing configurations
• Provides rail-to-rail output capability for single-supply operation
• Features low quiescent current for power-efficient applications

Applications

• Battery management systems
• Power supply monitoring
• Industrial process control

Procurement Notes

Verify the specific suffix IDBVT confirms the SOT-23-5 surface-mount package and tape-and-reel shipping format. Confirm RoHS compliance status as indicated in official documentation. Check for obsolescence notices, as some listings indicate end-of-life status for this component. Ensure the B3 grade matches required accuracy specifications for the design.

Selection Notes

Select this part when a fixed gain of 100 V/V is required for precise current measurement. The wide common-mode voltage range allows flexibility in circuit topology. Consider the 260 uA supply current for battery-powered designs. Verify that the SOT-23-5 package fits the board space constraints. Compare against other INA180 variants if different gain values or automotive qualification are needed.

Part Context

This component belongs to the INA180 family of current sense amplifiers designed for low-cost, low-power applications. The family offers various gain options and packaging styles. The B3 variant specifically denotes a fixed gain of 100 V/V. It is intended for general-purpose current sensing where moderate precision and wide common-mode range are sufficient.

Replacement Considerations

INA180B3QDBVRQ1 is an automotive-grade alternative with AEC-Q100 qualification. Other INA180 variants offer different fixed gains such as 20 V/V, 50 V/V, or 200 V/V.
