GENERAL DESCRIPTION
The OP282/OP482 dual and quad operational amplifiers feature
excellent speed at exceptionally low supply currents. Slew rate
exceeds 7 V/ s with supply current under 250 A 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 picoamps 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 applica-
tions. 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.
