The LMV118 (single) rail-to-rail output voltage feedback amplifiers 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 supply rail, allowing wide dynamic range especially in low voltage 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 independent 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 multiplexing 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.
