OP282: Dual/Quad Low Power, High Speed JFET Operational Amplifiers
The OP-282/OP482 dual and quad operational amplifiers feature excellent speed at exceptionally low supply currents. Slew rate exceeds 7 V/µs with supply current under 250 µA per amplifier. these unity gain stable amplifiers have a typical gain bandwidth of 4 MHz.
The JFET input stage of the OP-282/OP-482 insures bias current is typically a few piocamps and below 500 pA over the full temperature range. Offset voltage is under 3 mV for the dual and under 4 mV for the quad.
With a wide output swing, within 1.5 volts of each supply, low power consumption and high slew rate, the OP-282/OP-482 are ideal for battery-powered systems or power restricted applications. An input common-mode range that includes the positive supply makes the OP-282/OP-482 an excellent choice for high-side signal conditioning.
The OP-282/OP-482 are specified over the extended industrial temperature range. Both dual and quad amplifiers are available in plastic and ceramic DIP plus SOIC surface mount packages.
