Fig. 12-29 In this circuit, a 0- to 5-V input produces a 0 to 10-kHz output with a linearity of 0.02%. Drift is about 40 ppm/℃. Maximum current consumption is about 135μA-far below most IC V/F converters. To trim, apply 50 mV and select a value (typical 21 kΩ) at the C1 input for a 100-Hz output. Then, apply 5 V and adjust the 50-kΩ trim for a 10-kHz output. Linear Technology Linear Applications Handbook 1990 p AN23-11.
