Circuit=20 using two Precision Monolithics OP-07 opamps provides precise full-wave=20 rectification by inverting negative-polarity input voltages and = operating as=20 unity-gain buff er for positive-polarity inputs. Applications include=20 positive-peak detectors, single-quadrant multipliers, and magnitude-only = measuring systems. For positive inputs, circuit simply operates as two=20 unity-gain amplifier stages. Negative input turns D1 off and D2 on, = changing=20 resistor currents precisely enough to give overall circuit gain of -1. = Design=20 equations are given.-D. Soderquist and G. Erdi, The OP-07 Ultra-Low = Offset=20 Voltage Op Amp-a Bipolar Op Amp That Challenges Choppers, Eliminates = Nulling,=20 Precision Monolithics, Santa Clara, CA, 1975, AN-13, p 10. =
