OP11 is a four-channel matched 741-type operational amplifier produced by Analog Devices. It has very low input offset voltage and very high common-mode rejection ratio, which can be used in the design of instrumentation amplifiers.
The Analog Devices OP11 is a quad matched 741-type operational amplifier housed in a single 14-lead DIP package. It is designed to be pin compatible with the LM148, LM348, RM4156, RM4158, and HA4741 amplifiers. The device features guaranteed matched offset voltage and common-mode rejection ratio, making it ideal for instrumentation amplifier designs.
