LMX3 Low Voltage Rail-to-Rail Op Amps STMicroelectronics LMX3 Low Voltage Rail-to-Rail Operational Amplifiers are a set of single, dual and quad low-voltage, general-purpose operational amplifiers. These devices can operate from 2.3V to 5.5V with a typical current consumption of 120μA per channel. The LMX3 series offers a rail-to-rail output and an input common-mode voltage that includes ground. The LMX3 series also exhibits a 1.3MHz gain bandwidth and can drive capacitive loads. The devices are stable while operating at unity gain. They are offered with industry standard pinouts in tiny packages.
