GENERAL DESCRIPTION

The OP11 provides four matched 741-type operational amplifiers

in a single 14-lead DIP package. The OP11 is pin compatible

with the LM148, LM348, RM4156, RM4158, and HA4741

amplifiers. The amplifier is matched for common-mode rejection

ratio and offset voltage which is very important in designing

instrumentation amplifiers. In addition, the amplifier is designed

to have equal positive-going and negative-going slew rates. This

is an important consideration for good audio system performance.

The OP11 is ideal for use in designs requiring minimum space

and cost while maintaining performance.
