Overview
The LM7372MRX is a high-speed, dual operational amplifier produced by Texas Instruments. It combines the slewing characteristics of current feedback amplifiers with the versatility of traditional voltage feedback amplifier configurations. This device is designed for applications requiring high slew rates, wide gain bandwidth products, and high output current. The LM7372MRX is ideal for video and high-speed signal processing, including applications such as xDSL, pulse amplifiers, video distribution, transformer drivers, and laser diode drivers. It operates on ±15 V power supplies, allowing for large signal swings and a greater dynamic range, and is also specified for ±5 V operation for portable applications. The LM7372MRX is built on TI's Advance VIP III (Vertically integrated PNP) complementary bipolar process.
