illustrate

LME49726 is a low-distortion, low-noise, rail-to-rail output op-amp for audio optimization, high performance, high fidelity applications, and fully specified. LME49726 provides excellent audio performance and superior audio signal amplification. LME49726 has a very low THD+N to easily meet demanding audio applications. To ensure that the most challenging loads are uncompromising drives, LME49726 provide output currents greater than 300mA at 5V. In addition, the dynamic range maximizes the load of 4mV2kΩ for any supply voltage within the output stage driver.

LME49726 has a supply voltage range of 2.5V to 5.5V. LME49726 input circuitry maintains excellent common-mode and supply rejection over this supply voltage range, as well as maintaining its low input bias current. LME49726 is stable unit gain.
