The rail- to- rail input and output characteristics of these CMOS op amps allow them to swing very close to their supply rails– +5V and ground.
By using both an inverting and noninverting amplifier output to swing only positive due to their not being capable of swinging below ground (0V), the op amps each act like a perfect rectifier. Due to its unique R-R input topology, the OPA364 exhibits very high linearity over its entire common- mode input voltage range. This absolute- value amplifier has a gain of 1V/V and has an input range of within a few mV of -5V to +5V. (Circuit is created by Neil P. Albaugh, TI- Tucson)
