STMicroelectronics 

LM124A-LM224A-LM324A

TYPICAL SINGLE - SUPPLY APPLICATIONS

NON-INVERTING DC GAIN

DC SUMMING AMPLIFIER

HIGH INPUT Z ADJUSTABLE GAIN DC

INSTRUMENTATION AMPLIFIER

e0 = e1 +e2 -e3 -e4

Where (e1 +e2) ≥ (e3 +e4)

to keep e0 ≥ 0V

LOW DRIFT PEAK DETECTOR

if R1 = R5 and R3 = R4 = R6 = R7

e0 = 1 + -2--R-R---2--1- (e2 -e1)

As shown e0 = 101 (e2 - e1).
