lm331+counter

Hello every one please send me a working Frequency to Voltage circuit using TC9400 or LM331 or LM2907/LM2917 with pcb and schematics for 0 to 5MHZ (500KHz). Please send the details also and tell me which capaciters to used (mica, papper or electrolite etc).

how lm331 works

DO YOUR F DONKEY WORK
SOUNDS LIKE YOU WANT A WHOLE PROJECT


SO WORK FOR IT!!!!

MAKE A PIC PROGRAM FOR 0 -1KHZ STEPS OF PWM UNIT
IN 1 KHZ STEPS +0 -100 STEP SELECTABLE IN INCRUMS OF 1 HZ

POST IT AS C CODE

THEN ASK FOR HELP

DONT BE LAME THINK IN STEPS UP OR DOWN PLEASE !

I COULD WRITE CODE LIKE THIS WITH MY EYES WELDED SHUT

best to think what you need from the vtfc you target voltage to freq ia same as vco

so make a model in the relevent app
and stop posting crap about v to f already i see 15 posts by you about whatg primaribly is an rt-counter as is all r-f units


about v to f v to f is 1/8 of a modern pll i/c for multistandard broudcast decode
v=r-~0 .

I totally agree with VSMVDD. How will you learn if you don't try?
