Product Details
INA181A2IDBVR – TI 26V Bidirectional Current-Sense Amplifier
INA181A2IDBVR is a Texas Instruments voltage-output, bidirectional current-sense amplifier designed for accurate low-side and high-side current measurement. With a -0.2V to +26V common-mode range, 50V/V fixed gain, bidirectional sensing capability and compact 6-pin SOT-23 package, it is suitable for power monitoring, motor control, battery systems, DC/DC converters, lighting control and overcurrent detection circuits.
Engineering note: Always verify the latest TI datasheet, shunt resistor value, REF pin bias, input common-mode voltage, output range and PCB layout before final production approval.
Component Overview
INA181A2IDBVR belongs to the TI INA181 family of bidirectional low- and high-side current-sense amplifiers. It measures the small differential voltage across a current-sense resistor and outputs an amplified voltage that can be read by an ADC, MCU, comparator or control loop.
Circuit Function & Design Role
Measures current flow in both directions when the REF pin is biased properly, making it useful for charge and discharge current sensing.
Allows current measurement on the supply side while the load remains referenced to system ground.
Can also be used near ground for current feedback, protection and load-current measurement.
The A2 gain option provides higher output scaling than A1, helping improve signal level when the shunt voltage is small.

TomatoElec Quality & Supply Notes
As an in-stock independent distributor and electronic components supplier, TomatoElec supports INA181A2IDBVR sourcing for engineering samples, production replenishment, urgent replacement and BOM purchasing. For current-sense amplifiers, correct gain option, package type and original sourcing are important because the device affects current measurement accuracy and protection behavior.
- Original component sourcing: support sourcing of original Texas Instruments amplifier ICs for customer BOM requirements.
- Inventory support: help customers confirm available stock, package condition, date code and shipment schedule.
- Gain option verification: confirm the A2 50V/V gain option before shipment, especially when comparing with INA181A1, INA181A3 or INA181A4 versions.
- BOM matching: verify gain, bidirectional sensing, common-mode range, supply voltage, package and temperature requirements before approving any substitute.
Replacement & BOM Matching Guidance
INA181A2IDBVR should not be replaced only by matching the current-sense amplifier category. Engineers should also compare gain, bidirectional sensing method, REF pin usage, common-mode voltage range, offset voltage, bandwidth, supply voltage, output swing, package, pinout and temperature range.
