Single_cell_V_F_converter_1_Hz_to_1_kHz

Fig． 12－11 This circuit operates from a single 1.5-Vbattery, with only 125-μA current drain, to provide a range from 1Hz to 1kHz. Drift is 250ppm/℃. Battery discharge introduces less than 1% error over 1000 hours of operation. To trim, set the input to 1.000V and adjust the 500-kΩ potentiometer for an output of 1.000 kHz.
