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.
