3 Description

The LMV116 (single) rail-to-rail output voltage

feedback amplifiers offer high-speed (45 MHz), and

low-voltage operation (2.7 V) in addition to micropower

shutdown capability (LMV118).

Output voltage range extends to within 20 mV of

either supply rail, allowing wide dynamic range

especially in low voltage applications. Even with low

supply current of 600 μA, output current capability is

kept at a respectable ±20 mA 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 turnoff current

to 15 μA. Both turnon and turnoff characteristics are

well behaved with minimal output fluctuations during

transitions, thus the device can be used in powersaving

mode, as well as multiplexing applications.

Miniature packages (5-pin and 6-pin SOT-23) are

further means to ease the adoption of these lowpower,

high-speed devices in applications where

board area is at a premium.
