Description

  • A Seven-Nanosecond Comparator Using Single Supply Operation for a simple charge pump-based 10MHz voltage-to-frequency converter has 40dB dynamic range, operates from 5V supply. A 0V to 2.5V input produces a 0Hz to 10MHz output with 40dB of dynamic range, 1% linearity and 400ppm/degree Celsius gain drift. Power supply rejection is 0.5% for 4.75V to 5.25V supply excursions

Key Features

  • Input Voltage
    0 to 2.5 V
  • Output Frequency
    0 to 10000 KHz
