LMV116/LMV118 Low Voltage, 45MHz, Rail-to-Rail Output Operational Amplifiers with Shutdown
Option
October 2003
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 600碌A(chǔ),
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 l5碌A(chǔ). 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.
