High slew rate operational amplifier  
NE/SE531  
DESCRIPTION  
PIN CONFIGURATIONS  
The 531 is a fast slewing high performance operational amplifier  
which retains DC performance equal to the best general purpose  
types while providing far superior large-signal AC performance. A  
unique input stage design allows the amplifier to have a large-signal  
response nearly identical to its small-signal response. The amplifier  
is compensated for truly negligible overshoot with a single capacitor.  
In applications where fast settling and superior large-signal  
bandwidths are required, the amplifier out-performs conventional  
designs which have much better small-signal response. Also,  
because the small-signal response is not extended, no special  
precautions need be taken with circuit board layout to achieve  
stability. The high gain, simple compensation, and excellent stability  
of this amplifier allow its use in a wide variety of instrumentation  
applications.

• Same low drift offset null circuitry as µA741  
• Small-signal bandwidth 1MHz  
• Large-signal bandwidth 500kHz  
FEATURES  
• 35V/µs slew rate at unity gain  
• True op amp DC characteristics make the 531 the ideal answer to  
all slew rate limited operational amplifier applications  
• Pin-for-pin replacement for µA709, µA748, or LM101  
• Compensated with a single capacitor
