The output from an analog transducer varies from 2V to 4V over the range of the input signal. This voltage is to be connected to the input of an A-D converter which has an input voltage range of 0-5V. The signal conditioning circuit is to be designed to optimise the resolution of the A-D converter.
An LED indicator is also required which will indicate when the level of the transducer output voltage is at, or above, 30% of the maximum output.
(a) Design an opamp circuit to condition the signal so that it varies in the range 0V to 1V.
(b) Design an opamp circuit to amplify the conditioned signal so that it now varies from 0V to 5V.
(c) Design an opamp circuit to produce an enabled output when the voltage is at, or above, 30% of it’s max.
output.
I appreciate all input, or even a point in the right direction....
