LME49740 www.ti.com SNAS377B – FEBRUARY 2007 – REVISED APRIL 2013 LME49740 Quad High-Performance, High-Fidelity Audio Operational Amplifier Check for Samples: LME49740 FEATURES DESCRIPTION • • • • • The LME49740 is part of the ultra-low distortion, low noise, high slew rate operational amplifier series optimized and fully specified for high-performance, high-fidelity applications. Combining advanced leading-edge process technology with state-of-the-art circuit design, the LME49740 audio operational amplifiers deliver superior audio signal amplification for outstanding audio performance. The LME49740 combines extremely low voltage noise density (2.7nV/√HZ) with vanishingly low THD+N (0.00003%) to easily satisfy the most demanding audio applications. To ensure that the most challenging loads are driven without compromise, the LME49740 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. 1 2 Easily Drives 600Ω Loads Optimized for Superior Audio Signal Fidelity Output Short Circuit Protection PSRR and CMRR Exceed 120dB (Typ) SOIC and PDIP Packages APPLICATIONS • • • • • • • • • Ultra High-Quality Audio Amplification High-Fidelity Preamplifiers High-Fidelity Multimedia State-of-the-Art Phono Pre Amps High-Performance Professional Audio High-Fidelity Equalization and Crossover Networks High-Performance Line Drivers High-Performance Line Receivers High-Fidelity Active Filters KEY SPECIFICATIONS • • • • • • • • • Power Supply Voltage Range: ±2.5V to ±17V THD+N (AV = 1, VOUT = 3VRMS, fIN = 1kHz) – RL = 2kΩ: 0.00003% (typ) – RL = 600Ω: 0.00003% (typ) Input Noise Density: 2.7nV/√Hz (typ) Slew Rate: ±20V/μs (typ) Gain Bandwidth Product: 55MHz (typ) Open Loop Gain (RL = 600Ω): 140dB (typ) Input Bias Current: 10nA (typ) Input Offset Voltage: 0.1mV (typ) DC Gain Linearity Error: 0.000009% The LME49740's outstanding CMRR (120dB), PSRR (120dB), and VOS (0.1mV) give the amplifier excellent operational amplifier DC performance. The LME49740 has a wide supply range of ±2.5V to ±17V. Over this supply range the LME49740’s input circuitry maintains excellent common-mode and power supply rejection, as well as maintaining its low input bias current. The LME49740 is unity gain stable. The Audio Operational Amplifier achieves outstanding AC performance while driving complex loads with values as high as 100pF. The LME49740 is available in 14-lead narrow body SOIC and 14-lead PDIP. Demonstration boards are available for each package. 1 2 Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.
