lm335 schematic
hi
i'm stuck in quite a simple problem. what i have to do is just take output voltage from lm335 temperature sensor and subtract 3 volts from it using lm741 subtractor.
the problem is:
when i measure LM335 sensor output standalone(not connected to subtractor circuit) it works fine and shows voltage change with temperature. but when i connect its output with lm741 subtractor, its output remains constant with temperature.can anybody help me about whats wrong?
thanx in advance
