INA180B1IDBVR

Overview

The INA180B1IDBVR is a single-channel current sense amplifier from Texas Instruments, housed in an SOT-23-5 package. It operates on a supply voltage ranging from 2.7 V to 5.5 V with a typical quiescent current of 260 µA. The device features a fixed gain of 20 V/V and supports a common-mode voltage range from -200 mV to 26 V. Key electrical specifications include a gain-bandwidth product of 350 kHz, a maximum input offset voltage of 100 µV, and a common-mode rejection ratio of 100 dB. It functions within an industrial 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 full dynamic range
• Delivers high precision with low input offset voltage and low noise density

Applications

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

Procurement Notes

Verify the specific suffix 'R' indicates reel packaging when ordering. Confirm the B1 grade matches required accuracy levels against datasheet tables. Ensure the SOT-23-5 footprint aligns with PCB design constraints. Check RoHS compliance status for environmental regulations. Validate operating temperature range requirements against industrial specifications.

Selection Notes

Select this component for applications requiring precise current measurement in space-constrained designs. The fixed 20 V/V gain simplifies external resistor networks. Consider the 26 V common-mode range for high-side sensing without level shifting. Evaluate the 350 kHz bandwidth against signal frequency needs. Compare power consumption against battery-operated system limits.

Part Context

This part belongs to the INA180 family of current sense amplifiers designed for cost-sensitive and space-limited applications. It shares architectural similarities with other members like the INA180B2IDBVR but differs in gain settings. The series targets general-purpose current monitoring where moderate precision suffices.

Replacement Considerations

INA180B1IDBVT offers identical electrical characteristics in a tube package variant.
