Fig. 12-2 In this circuit, the voltage input is applied to the noninverting input of the LF356, and the LTC1043 is connected in the LF356 feedback loop. This results in a V/F where the oscillation frequency is directly related to input voltage with a transfer linearity of 0.005%. To trim, apply 3.0 V, and adjust gain trim for a 30-kHz Output.
