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).
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 (SOT-23-5 & SOT-23-6) are
further means to ease the adoption of these low
power high speed devices in applications where
board area is at a premium.
