LME49740NA

TEXAS INSTRUMENTS  LME49740NA  音频功率放大器, 4通道, ± 2.5V 至 ± 17V, DIP, 14 引脚

The is a quad high performance high fidelity audio 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 LME49740 audio operational amplifier delivers superior audio signal amplification for outstanding audio performance. The op-amp combines extremely low voltage noise density with vanishingly low THD+N to easily satisfy the most demanding audio applications. To ensure that the most challenging loads are driven without compromise, the op-amp 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 2kR loads to within 1V of either power supply voltage and to within 1.4V when driving 600R loads. The op-amp"s outstanding CMRR 120dB, PSRR 120dB and VOS 0.1mV give amplifier excellent operational amplifier DC performance. This op-amp is unity gain stable.
