MAX9918

-20V to 75V Input Range, Precision Uni-/Bidirectional, Current-Sense Amplifiers

General Description The MAX9918/MAX9919/MAX9920 are single-supply, high-accuracy current-sense amplifiers with a high input common-mode range that extends from -20V to +75V. These amplifiers are well suited for current moni toring of inductive loads such as motors and solenoids, where common-mo

-20V至+75V输入范围、高精度单/双向电流检测放大器

MAX9918/MAX9919/MAX9920为单电源、高精度检流放大器,具有高输入共模范围,可扩展至-20V至+75V。这几款放大器非常适合用于电机和螺线管等感性负载的电流监测,在此类应用中,电感电压反冲、电池反接或瞬态电压会导致产生负的共模电压。\n\n MAX9918/MAX9920通过外部电阻分压网络调节增益设置,MAX9919具有45V/V (MAX9919F)和90V/V (MAX9919N)的固定增益。VREFIN = GND时,MAX9918/MAX9919/MAX9920工作在单向放大器配置;VREFIN = VCC/2时,工作在双向放大器配置。MAX9920在输入 • 降低高电感反冲电压的保护性箝位\n• -20V至+75V输入共模电压范围\n\n\n\n• 支持较宽范围的高精度交流和直流电流检测应用\n• 单向或双向电流检测\n• 0.6% (最大值)增益误差 \n• 400µV (最大值)输入失调电压 \n• -3dB带宽为120kHz(MAX9919N) \n• 双向OUT的基准输入 \n• 满摆幅输出\n\n\n\n• 节省电路板面积 \n• 8引脚SOIC封装 \n• 单电源供电(4.5V至5.5V)\n\n\n\n• AEC-Q100认证(仅限MAX9918ASA/V+、MAX9919FASA/V+、MAX9919NASA/V+、MA;
