The OPAx340 amplifier is a single-supply, CMOS operational amplifier with 5.5-MHz unity-gain bandwidth and supply current of 950 μA. Its performance is optimized for low-voltage (2.7 V to 5.5 V), single-supply applications, with its input common-mode voltage linear range extending 300 mV beyond the rails and the output voltage swing within 5 mV of either rail. The OPAx340 series features wide bandwidth and unity-gain stability with rail-torail input and output for increased dynamic range. Power-supply pins must be bypassed with 0.01-μF ceramic capacitors.
