LM7372

High Speed, High Output Current, Dual Operational

Amplifier

General Description

The LM7372 is a high speed dual voltage feedback amplifier

that has the slewing characteristic of current feedback am-

plifiers; yet it can be used in all traditional voltage feedback

amplifier configurations.

The LM7372 is stable for gains as low as +2 or −1. It

provides a very high slew rate at 3000V/µs and a wide gain

bandwidth product of 120MHz, while consuming only

6.5mA/per amplifier of supply current. It is ideal for video and

high speed signal processing applications such as xDSL and

pulse amplifiers. With 150mA output current, the LM7372

can be used for video distribution, as a transformer driver or

as a laser diode driver.
