Texas Instruments High-Performance Analog Instrumentation, Op Amps, Buffer Amps INA290A3IDCKT

The INA290A3IDCKT is a single-channel current-sense amplifier designed for ultra-precise voltage drop measurements across shunt resistors. It operates over a wide common-mode voltage range of 2.7 V to 120 V and features a maximum offset voltage of ±12 µV, ensuring high accuracy in current measurement. The device offers a gain error of ±0.1% and a gain drift of ±5 ppm/°C, making it suitable for applications requiring precise current sensing. With a bandwidth of 1.1 MHz and a slew rate of 2 V/µs, the INA290A3IDCKT is capable of handling both DC and high-speed applications, such as fast overcurrent protection. The amplifier is packaged in a compact SC-70 format, measuring 2.00 mm x 1.25 mm, and consumes a quiescent current of 370 µA per channel. It is suitable for various applications, including active antenna systems, macro remote radio units, and server power supplies. The device operates effectively across an extended temperature range of -40°C to +125°C.
