DESCRIPTION  
The THS4524 is a very low-power, fully differential operational amplifier with rail-to-rail output and an input  
common-mode range that includes the negative rail. This amplifier is designed for low-power data acquisition  
systems and high-density applications where power dissipation is a critical parameter, and provide exceptional  
performance in audio applications.
