INA180B3IDBVR

Overview

The INA180B3IDBVR 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 typical quiescent current of 260 uA. The device features a fixed gain of 100 V/V and supports bidirectional current sensing. Key electrical specifications include a common-mode voltage range of -200 mV to 26 V, a gain error of 0.1%, and a CMRR of 100 dB. It offers a gain-bandwidth product of 150 kHz and an input offset voltage of 100 uV.

Feature Summary

• Supports bidirectional current sensing for both high-side and low-side applications
• Provides high accuracy with a fixed gain of 100 V/V and low gain error
• Operates over an extended industrial temperature range from -40°C to +125°C

Applications

• Battery management systems
• Power supplies
• Load switches
• Overcurrent protection circuits

Procurement Notes

Verify the specific suffix IDBVR corresponds to the SOT-23-5 package and reel/cut-tape availability. Confirm RoHS compliance status through official documentation. Ensure the B3 grade matches required precision levels for the design. Cross-reference the manufacturer part number against authorized distributor listings to avoid counterfeit components.

Selection Notes

Select this component when a compact SOT-23-5 footprint is required for current monitoring. The fixed 100 V/V gain simplifies resistor selection in signal conditioning stages. Consider the 26 V common-mode limit for high-side placement. The low power consumption suits battery-operated devices. Verify that the 150 kHz bandwidth meets the dynamic response requirements of the target application.

Part Context

This device belongs to the INA180 family of current sense amplifiers designed for cost-sensitive and space-constrained applications. It shares functional similarities with other members like the INA180A3IDBVR but differs in initial accuracy grades. The family targets general-purpose current monitoring where moderate precision and low power are prioritized over ultra-high speed or extreme accuracy.

Replacement Considerations

INA180A3IDBVR offers similar functionality with potentially different accuracy grades. INA181 series provides alternative gain options and pinout configurations. Check datasheets for exact parameter matching before substitution.
