Brand: Fairchild
The Fairchild 220 B is an integrated circuit (IC) that was popular in the 1970s and '80s for implementing analog functions such as amplification, filtering, and voltage regulation. It's a versatile device, capable of operating as a two-stage amplifier, a buffer, or a voltage regulator, depending on the configuration of its inputs and outputs. The Fairchild 220 B version in particular offers improved noise performance over previous iterations of the device, making it well-suited for use in applications such as audio electronics, instrumentation, and control systems. The IC consists of a number of components such as differential amplifiers, operational amplifiers, and voltage references, and can be paired with other similar devices to create more complex circuits. Its form factor, with a 14-pin DIP package, also makes it easy to integrate into PCB designs.
