Circuitry for 0.02%, 10kHz Voltage-to-Frequency Converter Requires Only 21mA Supply Current

Circuitry for 0.02%, 10kHz Voltage-to-Frequency Converter Requires Only 21mA Supply Current. A 0V to 5V input produces a 0Hz to 10kHz output, with a linearity of 0.02%. Gain drift is 60ppm/degree Celsius. Maximum current consumption is only 21uA, over 100 times lower than currently available monolithic ICs
