Maximum Transistor Frequency Posted by Druzyek in forum: This version is well suited for single speed or frequency switching or fully buffered frequency to voltage conversion applications. The LM, LM series are monolithic frequency to. The two basic configurations offered include an 8-pin device with a ground referenced tachometer input and an internal connection between the tachometer output and the op amp non-inverting input.
