7.3.1 Rail-to-Rail Inputs

Unlike many chopper amplifiers, the OPAx186 has rail-to-rail inputs that allow the input common-mode voltage to not only reach, but exceed the supply voltages by 200 mV. This configuration simplifies power-supply requirements by not requiring headroom over the input signal range.

The OPAx186 is specified for operation from 4.5 V to 24 V (±2.25 V to ±12 V) with rail-to-rail inputs. Many specifications apply from –40°C to +125°C.
