LM7372
LM7372 is High Speed/ High Output Current/ Dual Operational Amplifier manufactured by National Semiconductor.
Description
The LM7372 is a high speed dual voltage feedback amplifier that has the slewing characteristic of current feedback amplifiers; 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 6.5m A/per amplifier of supply current. It is ideal for video and high speed signal processing applications such as x DSL and pulse amplifiers. With 150m A 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™ III (Vertically integrated PNP) plementary bipolar process.
