5G23 operational amplifier

Overview

5G23 is a general-purpose operational amplifier developed by Shanghai Component Factory No. 5 in the 1970s.

Compared with F001, it only has two more equivalent transistors, but its balanced performance is greatly improved, with a larger input range, lower output impedance, looser power requirements, and no need to connect a ground wire.

In terms of circuit structure, F004 may be the first integrated operational amplifier independently developed in my country (F001-F003 are all imitation foreign models).

This project uses discrete components to build the computing amplifier, which is available for actual testing.

After the production is completed, a breadboard is used for testing, and an oscillator containing a Schmitt trigger is built. The output is connected to an LED, and you can see the LED flashing.
