OP282

双/四通道，低功耗，高速JFET运算放大器 Dual/Quad Low Power, High Speed JFET Operational Amplifiers

Product Details

The /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 OP282/OP482 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 OP282/OP482 are ideal for battery-powered systems or power restricted applications. An input common-mode range that includes the positive supply makes the OP282/OP482 an excellent choice for high-side signal conditioning.

The Op282/OP482 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.
