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.
