Need a 0-10V and 0-5V programmable power supplies

[help_me]

hi, i need two circuit first need circuit 0-5V programmable power suplly second nedd circuit 0-10V programmable power supply,this is my homework pls help me thanks you for interesting

0-10v power supply

You have to be more specific on how much current these power supplies should be able to deliver ..
0-5V or 0-10V can be easily produce by a 5 or 10V batery and a potentiometer (variable resistor) ..

0-10v variable power supply

not important current √

i want power supply for between 0-10V and 0-5V programmable

 

[IanP]

0-10v to 0-5v

If current is not important then use digital potentiometer ..

10v variable power supply

you can send circuit schema for two circuits?

 

[IanP]

power supply 10v and 5 v

So be it ..

0-10v regulator

since u say programmable first use a microcontroller to produce accurate signals for a dac.....next use an R-2R ladder as dac......u ll get 0-5V supply....10...or 12...or....even ...16 bits
dac can be produced......(although ∞ is the limit)......now use an amplifier to get 0-10V supply......if u have shortage of pins then u can use shift registers like 4094....
on contrary ......using 4094 at 10 volts can be use to connect to the R-2R ladder giving full fledged 0-10V power supply....(opamp on 10V supply)...
u can use a voltage follower if u want.....



or use a variable regulator...lm317....

voltage regulator 0-5v

Take a look to Adjustable Regulator datasheets like the LM317.

Added after 12 minutes:

OOOOH!!! you meant PROGRAMABLE not ADJUSTABLE... my mistake... sorry

 

[help_me]

dac 0-10v

ohhh sorry i wrong write , i wanna mean ADJUSTABLE power supply

 

[diemilio]

adjustable power supply 0-10v

ohhh sorry i wrong write , i wanna mean ADJUSTABLE power supply

So check any voltage regulator. On the application notes you find how to generate 0V outputs, whichi is like the "hardest" part to do.
If you need to get your input voltage for the power line just use a transformer (with the apropriate voltage relationships), diode rectifier and a simple filter to generate it.

dac output 0-10v supply 5v

You may use attached circuit.

Replace the 5kOhm potentiometer with:
*** 2kOhm one parallel with 3.3kOhm resistor to achive 10V at maximum
*** 2kOhm one parallel with 1kOhm resistor to achive 5V at maximum

0 to 5 volt variable power supply

you shoud concern with that site

digital potentiometer 0-10v

Use one potentiometer with an op-amp in volage buffer configuration and use a transistor in the output stage for current drive.
