I am counting TTL pulses then converting the count using the ad7524. I need to amplify my output with a gain of +7.5, however the typical operating circuit diagram has an inverting op amp. Is it possible to have positive gain with one op amp or should I use two inverting amps in series (the first being connected as in figure 4 of the data sheet and the second simply having a gain of -1)? By the way I am using the ad745 since it has low noise amplification.
Again referencing figure 4 in the data sheet, what is the output gain given the values of R1 and R2?
Thanks for the feedback.
