LM7372MR

LM7372MR Description

The LM7372MR from Texas Instruments is a high-performance, dual-channel voltage feedback operational amplifier designed for demanding applications requiring wide bandwidth and high slew rate. Operating within a 9V to 36V supply range, this IC delivers 120 MHz gain bandwidth product (GBW) and an exceptional 3000V/µs slew rate, making it suitable for high-speed signal processing. With 220 MHz -3dB bandwidth and 260 mA output current per channel, the LM7372MR excels in driving low-impedance loads while maintaining stability. Its low input bias current (2.7 µA) and 2 mV input offset voltage ensure precision in sensitive circuits. Packaged in an 8-SOPWRPAD tube, this obsolete but robust amplifier remains a reliable choice for legacy designs.
