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/¬8C, 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¬8C to +125¬8C.
