Is Now Part of To learn more about ON Semiconductor, please visit our website at www.onsemi.com Please note: As part of the Fairchild Semiconductor integration, some of the Fairchild orderable part numbers will need to change in order to meet ON Semiconductor’s system requirements. Since the ON Semiconductor product management systems do not have the ability to manage part nomenclature that utilizes an underscore (_), the underscore (_) in the Fairchild part numbers will be changed to a dash (-). This document may contain device numbers with an underscore (_). Please check the ON Semiconductor website to verify the updated device numbers. The most current and up-to-date ordering information can be found at www.onsemi.com. Please email any questions regarding the system integration to Fairchild_questions@onsemi.com.

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. 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 8-DIP 1 Internal Block Diagram Rev. 1.0.0 ©2001 Fairchild Semiconductor Corporation KA331 Absolute Maximum Ratings (TA = 25°°C) Parameter Symbol Supply Voltage Input Voltage Operating Temperature Range Power Dissipation Value Unit VCC 40 V VI -0.2 ~ + VCC V TOPR 0 ~ +70 °C PD 500 mW Electrical Characteristics Symbol Conditions VFC Non-Linearity Parameter VFCNL 4.5 ≤ VCC ≤ 20V Conversion Accuracy Scale Factor ACCUR Chang Of Gain With VCC Rated Full - Scale Frequency VCC∆G/VCC f Min.
