LME49724MR

LME49724MR Description

The LME49724MR from Texas Instruments is a high-performance audio operational amplifier designed for precision audio applications. This obsolete surface-mount IC features a single-circuit design in an 8-SOPWRPAD package, offering differential output with exceptional signal fidelity. Operating within a 5V to 36V supply range, it delivers 50 MHz gain bandwidth product (GBW) and a slew rate of 18V/µs, ensuring high-speed signal processing with minimal distortion. With low input bias current (60 nA) and input offset voltage (200 µV), it excels in applications demanding accuracy and low noise. Its 80 mA output current capability and 10 mA supply current make it suitable for driving demanding loads while maintaining efficiency.
