INA181A1IDBVT Description

Short technical summary and product information.

The Texas Instruments INA181A1IDBVT is a cost-optimized, bi-directional current-sense amplifier designed for applications requiring precise current monitoring. It operates with common-mode voltages ranging from -0.2 V to +26 V, independent of the supply voltage.

 

This amplifier offers a high bandwidth of 350 kHz, making it suitable for dynamic current measurements. Key electrical specifications include a maximum offset voltage of ±150 µV at 0 V common-mode and ±500 µV at 12 V common-mode. The device provides an output slew rate of 2 V/µs and a maximum gain error of ±1%.

 

Designed for ease of integration, the INA181A1IDBVT comes in a compact SOT-23 package with 6 pins. It operates within an industrial temperature range of -40°C to 125°C. The amplifier family is known for its low quiescent current, making it an efficient choice for power-sensitive designs.
