Working Principle of the ALD1722GSAL

The ALD1722GSAL amplifies electrical signals by using a variation on the common-emitter (CE) amplifier configuration. It is comprised of two transistors: the driver transistor and the output transistor. The driver transistor is controlled by the incoming signal, and its output is then directed to the output transistor, which is responsible for amplifying the signal.

The output transistor acts as an emitter-follower, meaning that its output voltage is in phase with its input voltage but with a much higher voltage gain (typically around 20x). This allows the ALD1722GSAL to amplify high voltages with minimal distortion. Additionally, the ALD1722GSAL also features built-in temperature compensation circuitry that helps to protect the amplifier from thermal derating.
