1 / 13 page LMV116/LMV118 Low Voltage, 45MHz, Rail-to-Rail Output Operational Amplifiers with Shutdown Option General Description The LMV116 (single) rail-to-rail output voltage feedback am- plifiers offer high speed (45MHz), and low voltage operation (2.7V) in addition to micro-power shutdown capability (LMV118). Output voltage range extends to within 20mV of either sup- ply rail, allowing wide dynamic range especially in low volt- age applications. Even with low supply current of 600µA, output current capability is kept at a respectable ±20mA for driving heavier loads. Important device parameters such as BW, Slew Rate and output current are kept relatively inde- pendent of the operating supply voltage by a combination of process enhancements and design architecture. For portable applications, the LMV118 provides shutdown capability while keeping the turn-off current to l5µA. Both turn-on and turn-off characteristics are well behaved with minimal output fluctuations during transitions. This allows the part to be used in power saving mode, as well as multiplex- ing applications. Miniature packages (SOT23-5 & SOT23-6) are further means to ease the adoption of these low power high speed devices in applications where board area is at a premium.
