摘要
本文介绍了基于电流检测芯片MAX4069实现对给定电压下的GPRS模块的耗电电流自动测量电路设计。通过该芯片将微弱电压信号放大,然后经过模数转换电路,即可以测得负载在给定电压下的电流。
This article introduces how to detect Voltage＇s Current based on MAX4069 automatically. A feebleness Voltage can be amplified through the chip, then the Voltage is sent to ADC for detecting. With this way , Vohage＇s Current can be calculated easily.
