GENERAL DESCRIPTION  
OP482  
11 V–  
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 of less than 250 µA  
per amplifier. These unity-gain stable amplifiers have a typical  
gain bandwidth of 4 MHz.

Figure 3. 14-Lead PDIP (P-Suffix) [N-14]  
The JFET input stage of the OP282/OP482 ensures that the bias  
current is typically a few picoamps and is less than 500 pA over  
the full temperature range. The offset voltage is less than 3 mV  
for the dual amplifier and less than 4 mV for the quad amplifier.

OP482  
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 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. The OP282 is available in the standard  
8-lead, narrow SOIC and MSOP packages. The OP482 is  
available in the PDIP and narrow SOIC packages, as well as  
a 14-ball WLCSP.
