OPA1688和OPA1689属于SoundPlus36V,单电源,低噪声运算放大器系列,该系列放大器能够在+ 4.5V(±2.25V)至+ 36V(这些最新补充的高压音频运动放大器与OPA16xx器件搭配,为用户提供了广泛的带宽,噪声和功率选择,可以满足各种应用的需要.OPA168x采用微型封装,并且偏移,漂移和静态电流均较低。这些器件还具有高带宽,快速转换率和高输出电流驱动能力。双路和四路版本具有相同的技术规格,可最大程度地提高设计灵活性。
大多数运算放大器仅有一个指定的电源电压,OPA168x系列则有所不同,其可在4.5V至36V的电压范围内额定运行。超过电源轨的输入信号不会导致反相。输入可在负电源轨以下100mV以及正电源轨2V之内正常运行。请注意这些器件可在正电源轨之上100mV的满轨到轨输入上运行,是在正电源轨2V之内运行时性能会受到影响。
OPA168x系列运算放大器的额定运行温度范围为-40°C至85℃。
