OP285  
GENERAL DESCRIPTION  
The OP285 is a precision high-speed amplifier featuring the  
Butler Amplifier front-end. This new front-end design com-  
bines the accuracy and low noise performance of bipolar  
transistors with the speed of JFETs. This yields an amplifier  
with high slew rates, low offset and good noise performance  
at low supply currents. Bias currents are also low compared  
to bipolar designs.  
The combination of low noise, speed and accuracy can be used  
to build high speed instrumentation systems. Circuits such as  
instrumentation amplifiers, ramp generators, bi-quad filters and  
dc-coupled audio systems are all practical with the OP285. For  
applications that require long term stability, the OP285 has a  
guaranteed maximum long term drift specification.  
The OP285 offers the slew rate and low power of a JFET  
amplifier combined with the precision, low noise and low  
drift of a bipolar amplifier. Input offset voltage is laser-trimmed  
and guaranteed less than 250 µV. This makes the OP285 useful  
in dc-coupled or summing applications without the need for  
special selections or the added noise of additional offset  
adjustment circuitry. Slew rates of 22 V/µs and a bandwidth  
of 9 MHz make the OP285 one of the most accurate medium  
speed amplifiers available.  
The OP285 is specified over the XIND—extended industrial—  
(–40°C to +85°C) temperature range. OP285s are available in  
8-pin plastic DIP and SOIC-8 surface mount packages.
