Rochester Electronics Linear - Amplifiers - Instrumentation, OP Amps, Buffer Amps INA2181A4QDGSRQ1

The INA2181A4QDGSRQ1 is a dual-channel, automotive-grade current-sense amplifier designed for applications requiring bidirectional current sensing. It is AEC-Q100 qualified, ensuring reliability in automotive environments with an operating temperature range of -40°C to +125°C. The device features a common-mode voltage range from -0.2 V to +26 V and offers a fixed gain of 200 V/V, making it suitable for high-precision measurements. With a maximum offset voltage of ±500 µV at 12 V common-mode voltage and a gain error of ±1%, the INA2181A4QDGSRQ1 provides accurate current sensing. The amplifier operates from a single power supply of 2.7 V to 5.5 V and has a quiescent current of 500 µA. Its high bandwidth of 350 kHz and output slew rate of 2 V/µs enable fast response times, making it ideal for applications such as motor control, battery monitoring, and power management. The device is packaged in a 10-pin VSSOP, facilitating integration into compact designs.
