LMV118 - Low Voltage, 45MHz, Rail-to-Rail Output Operational Amplifiers with Shutdown Option

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 micro-power 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 power-saving mode, as well as multiplexing applications. Miniature packages (5-pin and 6-pin SOT-23) are further means to ease the adoption of these low-power, high-speed devices in applications where board area is at a premium.
