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 am­plifiers offer high speed (45MHz), and low voltage operation (2.7V) in addition to micro-power shutdown capability (LMV118).
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.
