+5VDC & -15VDC FROM +15VDC SUPPLY QUESTION FOR ANALOG AD570 A/D CONVERTER
REASON I ASK IS I DON'T KNOW 100% FOR SURE? ANY ENGINEER'S ANSWER.
FROM +15VDC I WANT TO POWER an AD570, DATASHEET SUGGESTS USING +5V AND -15V SUPPLY.
CAN I DO THIS WITH 'CONDOR B15-1.5' (OUTPUT 15VDC@1.5 AMPS) D.C. POWER SUPPLY'S OUTPUT CONNECTED TO 3 ELEMENT SERIES RESISTOR “VOLTAGE DIVIDER” Et=15=E1+E2+E3 15=5+5+5 (USING 10K OHM ELEMENTS)
OK, Et=E1+E2+E3 GIVEN THAT, HOW DO I “SPLIT” THE SUPPLY, HOW DO I GET NEGATIVE VOLTS OR POTENTIAL DIFFERENCE; DO I REVERSE THE POLARITY? DO I INVERT THE Vs CONNECTIONS, DO I TREAT 0VDC, THE POWER SUPPLY GROUND I GUESS, AS -15VDC?
0VDC AND -15VDC, HOW DO I GET THAT? CAN I GET THAT FROM PRIMARY CELLS IN SERIES IN BATTERY HOLDERS? DRAW ME A SCHEMATIC?
I JUST NEED A SIMPLE ANSWER.
I CAN SUPPLEMENT THIS TEXT WITH A PLETHORA PICTURES TAKEN BY A CELL PHONE CAMERA, BUT I DONT LIKE USING MY TIME LIKE THAT FOR A SIMPLE QUESTION LIKE THIS, THAT WOULD BE FUNNY.
I TRIED MY HAVING MY PARTS SUPPLIER TECHNICAL SUPPORT ANSWER THIS OVER THE PHONE.
“IS 100nF=.01uF?”
'YES.'
“BINGO.”
