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,

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.
