简介:
《MAX4080》是一份详尽的技术文档,专注于Maxim Integrated公司生产的MAX4080运算放大器。该器件以卓越的性能和低功耗著称,在多种电子应用中发挥关键作用。文档内详细阐述了其工作原理、电气特性及应用场景。
The MAX4080/MAX4081 are high-side current-sense amplifiers with an input voltage range from 4.5V to 76V, making them suitable for applications in telecom, automotive, backplane systems, and other environments where monitoring high-voltage currents is crucial. The MAX4080 is designed for unidirectional current sensing while the MAX4081 supports bidirectional current sensing. The single output pin of the MAX4081 continuously monitors transitions between charging and discharging states without requiring a separate polarity output. For the MAX4081, an external reference is needed to set the zero-current output level (VSENSE = 0V). During charging, the output voltage ranges from VREF to VCC; during discharge, it ranges from VREF to GND.
