Input Buffer Amplifier Open-Loop Alarm Optional External Pass Transistor to Reduce Self-Heating Errors 0.002% Typ Nonlinearity PRODUCT DESCRIPTION The AD694 is a monolithic current transmitter that accepts high level signal inputs to drive a standard 4–20 mA current loop for the control of valves, actuators, and other devices com- monly used in process control. The output is connected to its inverting input, and the signal source is connected to the non-inverting input. Depending on the external connections, the internal resistor network may be used to provide either a fixed gain of +2 video buffer or a gain of +1 or –1 voltage buffer. For example, in AM radio receivers the I.F. A buffer amplifier (or voltage follower) is a circuit designed to only replicate the input voltage, not the current. 2 Description The G123-815 Buffer Amplifier interfaces between standard PLC analogue input and output modules, on one side, and a position transducer and a Moog valve, on the other. 20130403 . Ie the input of a buffer amplifier places a minimal load on the connected circuit. This is negative feedback.
