LME49721

LME49721 High Performance, High Fidelity Rail-to-Rail Input/Output Audio Operational Amplifier October 2007 LME49721 High Performance, High Fidelity Rail-to-Rail Input/Output Audio Operational Amplifier General Description The LME49721 is a low distortion, low noise Rail-to-Rail Input/ Output operational amplifier optimized and fully specified for high performance, high fidelity applications. Combining advanced leading-edge process technology with state-of-the-art circuit design, the LME49721 Rail-to-Rail Input/Output operwww.DataSheet4U.com ational amplifier delivers superior signal amplification for outstanding performance. The LME49721 combines a very high slew rate with low THD+N to easily satisfy demanding applications. To ensure that the most challenging loads are driven without compromise, the LME49721 has a high slew rate of ±8.5V/μs and an output current capability of ±9.7mA. Further, dynamic range is maximized by an output stage that drives 10kΩ loads to within 10mV of either power supply voltage. The LME49721 has a wide supply range of 2.2V to 5.5V. Over this supply range the LME49721’s input circuitry maintains excellent common-mode and power supply rejection, as well as maintaining its low input bias current. The LME49721 is unity gain stable. ■ Gain Bandwidth Product ■ Open Loop Gain (RL = 600Ω) ■ Input Bias Current ■ Input Offset Voltage ■ PSRR 20MHz (typ) 118dB (typ) 40fA (typ) 0.3mV (typ) 103dB (typ) Features ■ Rail-to-rail Input and Output ■ Easily driv...
