OPA2349EA/250

The OPA2349EA/250 is an ultra-low power CMOS Operational Amplifier for use with PCMCIA cards. This rail-to-rail input and output amplifier is specifically designed for battery-powered applications. The input common-mode voltage range extends 200mV beyond the power-supply rails and the output swings to within 350mV of the rails, maintaining wide dynamic range. Unlike some MicroPower op amp, these parts are unity-gain stable and require no external compensation to achieve wide bandwidth. The OPA349 features a low input bias current that allows the use of large source and feedback resistors. The OPA349 can be operated with power supplies from 1.8 to 5.5V with little change in performance, ensuring continuing superior performance even in low battery situations.
