LM7372

SNOS926F – MAY 1999 – REVISED SEPTEMBER 2014

LM7372 High Speed, High Output Current, Dual Operational Amplifier

1 Features

3 Description

The LM7372 is a high speed dual voltage feedback

1

•

−80 dBc Highest Harmonic Distortion @1 MHz,

amplifier with the slewing characteristic of current

feedback amplifiers. However, it can be used in all

•

Very High Slew Rate: 3000 V/µs

traditional voltage feedback amplifier configurations.

•

Wide Gain Bandwidth Product: 120 MHz

The LM7372 is stable for gains as low as +2 or

−1. It

•

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

•

Low Supply Current: 13 mA (both amplifiers)

wide gain bandwidth product of 120 MHz, while

consuming only 6.5 mA/per amplifier of supply

•

High Open Loop Gain: 85 dB

current. It is ideal for video and high speed signal

•

High Output Current: 150 mA

processing applications such as xDSL and pulse

•

Differential Gain and Phase: 0.01%, 0.02°

amplifiers. With 150 mA output current, the LM7372

can be used for video distribution, as a transformer

driver or as a laser diode driver.

2 Applications

•

HDSL and ADSL Drivers

Operation on ±15 V power supplies allows for large

signal swings and provides greater dynamic range

•

Multimedia Broadcast Systems

and signal-to-noise ratio. The LM7372 offers high

•

Professional Video Cameras

SFDR and low THD, ideal for ADC/DAC systems. In

•

CATV/Fiber Optics Signal Processing

addition, the LM7372 is specified for ±5 V operation

for portable applications.

•

Pulse Amplifiers and Peak Detectors

•

HDTV Amplifiers

The LM7372 is built on TI's Advance VIP™ III

(Vertically integrated PNP) complementary bipolar

process.
