The original NS LME49720 USA have a fever stage double operational amplifier, dual in line 8 feet.
American half the country launched The operational amplifier has a very low voltage noise density (2. 7 u v / Hz / 2), is currently the lowest noise dual operational amplifiers, thd + n is only 0.00003%. and high gain bandwidth product (55mhz) can easily meet the most demanding audio application requirements. LME49720 has the ability of 45mA current output, can smoothly drive the most difficult to respond to the load. LME49720 working voltage range is wide, about + 2.5V a + 17V, unity gain stable and reliable, does not appear self and unstable working condition. At the same time, the input circuit of the common mode rejection ratio (CMRR) and power suppression ratio (PSRR) up to 108db above, the input bias current low to 1O Mu a. In addition, the output short-circuit protection function. Is a dedicated Audio Dual OP AMP highly cost-effective.
