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 ampli-
fiers; 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 ampli-
fier 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 VIP
integrated PNP) complementary bipolar process.
