OP282GP

The OP282/OP482 series from Analog Technologies are dual and quad JFET input operational amplifiers designed for high speed at exceptionally low supply currents. These amplifiers boast a slew rate exceeding 7 V/μs with supply current under 250 μA per amplifier, and a typical gain bandwidth of 4 MHz. The JFET input stage ensures very low bias current, typically a few picoamps, and an offset voltage under 3 mV for the dual and under 4 mV for the quad.

With a wide output swing, low power consumption, and high slew rate, the OP282/OP482 are well-suited for battery-powered systems or power-restricted applications. Their input common-mode range includes the positive supply, making them an excellent choice for high-side signal conditioning. These devices are specified over the extended industrial temperature range and are available in DIP and SOIC surface mount packages.

Key electrical characteristics include a typical gain bandwidth of 4 MHz and a high slew rate of 9 V/μs. The low supply current of 250 mA per amplifier and low offset voltage of 3 mV make them efficient for various applications. The JFET input stage provides a low input bias current of 100 pA.

Applications for the OP282/OP482 include active filters, fast amplifiers, integrators, and supply current monitoring. The devices are unity gain stable and offer a common-mode range that includes the positive supply rail.
