The OP282/OP482 dual and quad operational amplifiers feature  
excellent speed at exceptionally low supply currents. The slew  
rate is typically 9 V/µs with a 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 ensures 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 V 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. The OP282 is available in the standard  
8-lead narrow SOIC and MSOP packages. The OP482 is  
available in PDIP and narrow SOIC packages.
