OPA1622是一款双通道,双极输入,SoundPlus音频运算放大器。该器件在1kHz频率下拥有
2.8nV /√ Hz 的超低噪声密度和-119.2dB的超低THD + N,同时还能够以100mW的输出功率驱动一个32Ω负载.OPA1622具有极高的交流电源抑制比(PSRR)和共模抑制比(CMRR)技术规格,可消除来自电源的噪声,因此非常适合便携音频应用。此外,该器件还具有+ 145mA /-130mA的高输出驱动能力。
OPA1622支持±2V到±18V的宽电源电压范围,每通道电源电流仅为2.6mA.OPA1622运算放大器的单位增益稳定,在宽范围负载条件下可保持出色的动态性能.OPA1622具有关断模式,允许放大器从正常运行状态切换至一个待机电流典型值低于5μA的状态。此关断特性专门用于消除进入或退出关断模式时的喀哒和噼啪噪声。
< p> OPA162 2内部采用独特布局,即使在过驱或过载条件下也可在通道间实现最低串扰和零交互。此器件的额定温度介于-40°C至+ 125°C之间。 < /DIV>
