INA180A3IDBVT

Overview

The INA180A3IDBVT is a single-channel current sense amplifier manufactured by Texas Instruments. It operates within a supply voltage range of 2.7 V to 5.5 V and supports a common-mode input voltage from -200 mV to 26 V. The device features a fixed gain of 100 V/V, a gain error of 0.1%, and an input offset voltage of 100 µV. Key electrical specifications include a bandwidth of 150 kHz, a power supply current of 260 µA, and a common-mode rejection ratio of 100 dB. It is housed in a SOT-23-5 package and functions across a temperature range of -40°C to +125°C.

Feature Summary

• Supports bidirectional current sensing with high-side and low-side monitoring capabilities
• Provides accurate measurement through a fixed internal gain of 100 V/V
• Enables operation over a wide common-mode voltage range extending below ground

Applications

• Battery management systems requiring precise current monitoring
• Industrial process control loops for load cell amplification
• Power supply output current regulation and protection circuits

Procurement Notes

Verify the specific suffix IDBVT corresponds to the SOT-23-5 surface-mount package configuration. Confirm that the A3 grade matches the required 100 V/V gain specification for your circuit design. Ensure compatibility with the intended operating temperature range and supply voltage constraints before finalizing procurement orders.

Selection Notes

Select this component when a fixed gain of 100 V/V is required for differential signal amplification in current sensing applications. It is suitable for designs needing a wide common-mode voltage range up to 26 V while maintaining low power consumption. Consider the SOT-23-5 footprint if space-constrained PCB layouts are a priority.
