hello friends
i want to use a summing amplifier so i googled then i found this (MC1458)
http://mediastudy.buffalo.edu/Roboti...heets/2172.pdf

what i want to get from this amplifier is (0.5 and -0.5) as outputs with inputs of (logic 0 or logic 1) so how can i connect this amplifier ?

then the outputs (0.5 or -0.5) will be an input to another amplifier with a gain of 38 ?how can i build the second amplifier?

sorry if my questions seem stupid and that because of self study of the electronics

thanks in advance

Bad link. However, If the first amp outputs +/-0.5V, and the second has a gain of 38, then the output of the second would have swing from -19V to +19V, which means it needs supplies of + and - 22V or so. You need a "high voltage" opamp; one which can run on >44V between Vcc and Vee.

What is your circuit to be used for?
