【文字介绍】

ADA4310-1内置两个高速电流回馈型运算放大器。它具有高输出电流、高带宽和快速压摆率,特别适合要求驱动低阻抗负载时提供高线性度性能的宽带应用。

ADA4310-1集成电源管理功能,可提供关断模式和/或优化放大器静态电流的能力。通过CMOS兼容型省电控制引脚(PD1和PD0),该器件可以采用四种工作模式:全功率、中等功率、低功率或完全关断。关断模式下,每个放大器的静态电源电流降至仅0.65 mA,同时放大器输出变为高阻抗状态。

ADA4310-1提供两种封装:一种是散热增强型10引脚MSOP封装,带有裸露焊盘以改善热传导;一种是散热增强型4 mm × 4 mm、16引脚LFCSP封装。额定工作温度范围为-40°C至+85°C工业温度范围。
