The LME49722 bines extremely low voltage noise density (1.9n V/√Hz) rate with vanishingly low THD+N (0.00002%) to easily satisfy the most demanding audio applications. To ensure that the most challenging loads are driven without promise, the LME49722 has a high slew rate of ±22V/µs and an output current capability of ±28m A. Further, dynamic range is maximized by an output stage that drives 2kΩ loads to within 1V of either power supply voltage. The LME49722 has a wide supply range of ±2.5V to ±18V. Over this supply range the LME49722 maintains excellent mon-mode and power supply rejection, and low input bias current. This Audio Operational Amplifier achieves outstanding AC performance while driving plex loads with values as high as 100p F with gain value greater than 2. Directly interchangeable with LME49720, LM4562 and LME49860 for similar operating voltages. Table 1.
