VFC121V / F converter application temperature measurement system

Published:2013/1/22 2:40:00 Author:Ecco | Keyword: converter application , temperature measurement system | From:SeekIC

VFC121 uses high-frequency NPN / PNP charge balance technology to realize V / F conversion, and its power supply is flexible( 4.5 to 36V), and the voltage output is proportional to absolute temperature, thus it can be used as the system environment temperature measurement for D / A converters, data acquisition and system deviating occasion. VFCl21 uses 0IP 14-pin double-row arrangement package, and its pinout and internal circuit block diagram is shown as below.
