3 Description
The LM7372 is a high speed dual voltage feedback
amplifier with the slewing characteristic of current
feedback amplifiers. However, 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 3000 V/µs and a
wide gain bandwidth product of 120 MHz, while
consuming only 6.5 mA/per amplifier of supply
current. It is ideal for video and high speed signal
processing applications such as xDSL and pulse
amplifiers. With 150 mA output current, the LM7372
can be used for video distribution, as a transformer
driver or as a laser diode driver.
Operation on ±15 V 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 ±5 V operation
for portable applications.
The LM7372 is built on TI's Advance VIP™ III
(Vertically integrated PNP) complementary bipolar
process.
