While I'm familiar with the method used in an inverting situation is there a way to use a single op amp to add two voltages? I'd hate to add another device to the design since I only have one amp left in the quad. Single supply of +5.0V
I have Signal A, which varies from 0 - +1.0 volts
I have Signal B, which will be used as an adjustable positive offset, from 0 - +1.0V
In other words let's say Signal A varies from 0 - 1V but I'm wanting to be able to add a positive DC offset to it.
Input A = 0V, B = 0.5V, Output = 0.5V
Input A = 0.5V, B = 0.5V, Output = 1.0V
Input A = 0.5V, Input B = 0.75V, Output = 1.25V
Input A = 0.75V, B = 0.25V, Output = 1.0V
Easy enough to do in the inverting configuration then invert it again, but with one amp?
I'll swear this is simpler than I think, I'm just not 100% again tonight.
