does anybody know how i can amplify LM35 output to about 10 volts?

 

Hello,

I found this post in the Electronics Tips and Tricks thread.

Now you have your own thread.

The LM35 is giving a signal of 10 mV / °C.
How much do you want to amplify the signal?

Hello,

I found this in an email:

Good day sir,

I need to amplify the output of LM35 to about 10V. the IC gives the output of10mV/ deg C and i need to measure 0-100 deg C. the maximum i can get is around 1V and i need to drive a load requiring 10v. any help will be appreciated,

thanks.

As I do not answer emails, I will do it here.

You will need an opamp that amplifies 10 times.
The powersupply must be higher than this 10 volts in order to work properly.
Best is to take an opamp with rail-to-rail in and output capability.
This spreadsheet contains a list of rail-to-rail opamps from national:
Operational_Amplifiers_|_Rail_to_Rail_Input.xls.txt
(remove the .txt and load it in excel from microsoft or in calc from the free open office).

Well, depending on what need for the output voltage controls my op amp gain. Simple as that.

What do you want for the output?
