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.
Operation on ±15V power supplies allows for large signal
swings and provides greater dynamic range and
signal-to-noise ratio. The LM7372 offers high SFDR and low
THD, ideal for ADC/DAC systems. In addition, the LM7372 is
specified for ±5V operation for portable applications.
The LM7372 is built on National’s Advance VIPIII (Verti-
cally integrated PNP) complementary bipolar process.
