伊萨拜棱辉特用于电池管系统的四通道数据采集系统基础芯片
1. General description
The IHM-A-1500 is a complete, low power data acquisition system for very small signals (i.e. voltages from shunt resistors, thermocouples) that operates on a single 5 V power supply. The chip powers up with a set of default conditions at which time it can be operated as a read-only-converter. Reprogramming is at any time possible by just writing into two internal registers via the serial interface.
