datasheet of ka331

KA331 V-F Converter
Features
• Guaranteed linearity: 0.01% max.
• Low power dissipation: 15mW at 5V
• Wide range of full scale frequency: 1Hz to 100KHz
• Pulse output compatible with all logic forms
• Wide dynamic range: 100dB min at 10KHz full scale frequency.

Description
This voltage to frequency converter provides  the  output
pulse train at a frequency  precisely  proportional  to  the
applied input voltage. The KA331 can operate  at  power
supplies as low as 4.0V and be changed output frequency
from 1Hz to 100KHz. It is ideally suited for use in  simple
low-cost  circuit  for analog-to digital  conversion,  long term
integration, linear  frequency modulation or  demodulation,
frequency-to-voltage conversion, and many other functions.
