OP27  
The OP27 precision operational amplifier combines the low  
offset and drift of the OP07 with both high speed and low noise.  
Offsets down to 25 μV and maximum drift of 0.6 μV/°C make  
the OP27 ideal for precision instrumentation applications.  
Exceptionally low noise, en = 3.5 nV/√Hz, at 10 Hz, a low 1/f  
noise corner frequency of 2.7 Hz, and high gain (1.8 million),  
allow accurate high-gain amplification of low-level signals.  
A gain-bandwidth product of 8 MHz and a 2.8 V/μs slew rate  
provide excellent dynamic accuracy in high speed, data-  
acquisition systems.

A low input bias current of 10 nA is achieved by use of a bias  
current cancellation circuit. Over the military temperature  
range, this circuit typically holds IB and IOS to 20 nA  
and 15 nA, respectively.  
The output stage has good load driving capability. A guaranteed  
swing of 10 V into 600 Ω and low output distortion make the  
OP27 an excellent choice for professional audio applications.
