INA281B2IDBVT Description

Short technical summary and product information.

The Texas Instruments INA281B2IDBVT is a high-precision current sense amplifier designed for accurate current monitoring. It features a wide operational common-mode voltage range from -4 V to 110 V, with survival voltages extending to -20 V and 120 V.

 

This amplifier boasts excellent accuracy with a maximum gain error of ±0.5% and a gain drift of ±20 ppm/°C. The input offset voltage is typically ±55 µV with an offset drift of ±0.1 µV/°C. It supports various voltage gains, including 20, 50, 100, 200, and 500 V/V.

 

With a high bandwidth of 1.3 MHz and a slew rate of 2.5 V/µs, the INA281B2IDBVT is suitable for demanding applications. It operates within an extended temperature range of -40°C to 125°C and has a low quiescent current of 1.5 mA (typical).

 

The device is available in a compact SOT-23 package, measuring 2.9 mm x 2.8 mm with an area of 8.12 mm². This small footprint makes it ideal for space-constrained designs. The amplifier is capable of low-side current sensing.
