The Texas Instruments INA281A1IDBVT is a high-precision current sense amplifier capable of measuring voltage drops across shunt resistors. It operates over a wide common-mode range of -4 V to 110 V, allowing for precise measurement of recirculating currents.
Key electrical specifications include a typical bandwidth of 1.3 MHz and a slew rate of 2.5 V/µs. The amplifier exhibits excellent Common Mode Rejection Ratio (CMRR), with 120 dB at DC and 65 dB at 50 kHz. Accuracy is maintained with a maximum gain error of ±0.5% and a gain drift of ±20 ppm/°C. Typical offset voltage is ±55 µV with a drift of ±0.1 µV/°C.
This device is available in a 5-pin SOT-23 package, suitable for surface mounting. It operates within an ambient temperature range of -40°C to 125°C. The INA281A1 variant offers a gain of 20 V/V.
The INA281A1IDBVT is designed for applications requiring accurate current monitoring in demanding environments, including automotive and industrial systems.
