Applications:

 

The Waddington Electronics V to F-1 Voltage to Frequency converter is a low cost industrial building block that can be used in process and machinery control applications.

 

Input voltage polarity is jumper selectable so positive or negative voltages can be converted, also by adding the optional offset adjustment Bipolar voltages can be converted.

Layout


     
 

Outputs can be either TTL or CMOS compatible and are set by connection of an external voltage to the pull up transistor of the open collector output transistor.
