DESCRIPTION (CONTINUED)
To ensure that the most challenging loads are driven without compromise, the LME49720 has a high slew rate of
±20V/μs and an output current capability of ±26mA. Further, dynamic range is maximized by an output stage that
drives 2kΩ loads to within 1V of either power supply voltage and to within 1.4V when driving 600Ω loads.
The LME49720's outstanding CMRR (120dB), PSRR (120dB), and V_OS (0.1mV) give the amplifier excellent
operational amplifier DC performance.
The LME49720 has a wide supply range of ±2.5V to ±17V. Over this supply range the LME49720’s input circuitry
maintains excellent common-mode and power supply rejection, as well as maintaining its low input bias current.
The LME49720 is unity gain stable. This Audio Operational Amplifier achieves outstanding AC performance while
driving complex loads with values as high as 100pF.
The LME49720 is available in 8–lead narrow body SOIC, 8–lead PDIP, and 8–lead TO-99. Demonstration
boards are available for each package.

These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam
during storage or handling to prevent electrostatic damage to the MOS gates.
