The picture is four independent benchmark voltage source circuit of LMl39.In the circuit,VD1 is used to generate benchmark voltage and comparator LM139 is the adjustable phase amplifier of four independent gains.RP1~RP4 are used to regulate the output voltage and the adjustable range is UZ≤UO≤UCC.In the formula,Uz is voltage regulating voltage of VD1 and R2~R5 are boost resistance of R2~R5 output ends.The current amplification transistor is connected to A1~A4 output ends if the output voltage is increased.
