GENERAL DESCRIPTION  
4V– (CASE)  
NC = NO CONNECT  
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 drift of 0.6 µV/°C maximum 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/µsec slew rate  
provides 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  
NC = NO CONNECT  
OP27 an excellent choice for professional audio applications.
