Ic cd4047 circuit datasheet 7805


Here goes the parts list. 1. 240V to 15V 1.2A Transformer 2. 4 pieces of IN4001 (You can use a bridge rectifier as well) 3. 220uF 25V Capacitor 4. .1uF 25V Capacitor 5. 7812 IC (Integrated Circuit) 6. A heat sink plate for 7812 IC 7812 is a very good voltage regulator integrated circuit (IC). Apr 13, 2013 · Variable resistor (RV1) is provided for adjusting the output frequency to exact 50Hz. The time period of the oscillation is given by the relation T = 4.40*R*C. For detailed working of the IC, please refer its datasheet. CD4047 has two outputs (pins 10 and 11) which are complementary to each other. (This is my understanding of the 7805 circuit. If my understanding of the ckt is wrong, please point me in the right direction) I think,,,,, The resistor R4 limits current through the zener diode D1 and maintains the voltage across it constant thereby biasing the transistor Q12 and thereby causing the voltage across the resistors R7, R6 to be constant as long as the current through the zener ... Irgendwie habe ich an einem Abend Mist gemessen. Das Signal vom DDS sah schlimm aus, weder Rechteck noch Sinus und mager. Es sah aber erst ganz am Ende der Kette an einem Schmitttrigger so schlimm aus. Also habe ich mal die Versorgungsspannung am IC gemessen, diese sah direkt am IC genauso wie dessen Ausgangssignal aus. protel99se常用封装库元件&分立元件库(三份资料汇总)资料一:1.电阻固定电阻:RES半导体电阻:RESSEMT电位计:POT变电阻:RVAR可调电阻:res1.电容定值无极性电容;CAP定值有极性电容;CAP半导体电容:CAPSEMI可调电容:CAPVAR3.电感:INDUCTOR4.二极管:DIODE.LIB发光二极管:LED5.三极管:NPN16.结型场效应管:JFET ...
