Dear all

is there anyone out there who can help me on this question which i faced.

I am tasked to design a circuit that comprises of a LM35 and an amplifier LM324. The LM324 is to amplifier the voltage produced by the temperature sensor by 10 times

the circuit is power by a 9V battery.


Many Thanks
:confused:

Hello,

What range do you want to measure with the LM35?
The LM35 has an output of 10 mV/°C.
Why do you want to amplify this with 10 times?
The maximum output voltage of an LM324 on 9 volts supply is 7.5 Volts.
