Dual Output, Buffered Reference (On Single 3V Supply)

Apr 18th 2003
The amplifier configuration establishes the reference voltage across the 75k resistor. A fixed current is then forced into the 46.4k resistor and sets the lower output voltage. The upper voltage output is greater than the lower voltage output by the reference voltage. ...



Dual Buffered ±0.617V Reference Powered by Two AA Batteries

Nov 1st 1983
Lower opamp is a precision inverter setting outputs to set the outputs at the same magnitude but opposite polarity. The upper opamp drives the positive output so that the difference of the two outputs is the reference voltage, so the result is that half the reference voltage is the magnitude of the outputs. ...
