LT1001 Precision Absolute Value Circuit

An absolute value circuit as as a full wave rectifier. Positive input
voltqges cause the first amplifier to act as a unity gain inverter. The second
amplifier inverts thiis output again to produce a positive outut voltage.
Negative input voltages cause the + input of the second amplifier to move
positive to a voltage of 2/3Vin. This is multiplied by a gain of 3/2 by the
second amplifier also producing a positive output voltage equal to the input
voltage.
