GENERAL DESCRIPTION

The OP11 provides four matched 741-type operational

amplifiers in a single 14-lead PDIP. 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, which 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.
