ad623 是一个集成单电源仪表放大器，它能在单电源( + 3v～ + 12v) 下提供满电源幅度的输出,ad623 允许使用单个增益设置电阻进行增益编程,以得到良好的用户灵活性。在无外接电阻的条件下,ad623 被设置为单位增益 外接电阻后,ad623 可编程设置增益,其增益最高可达1000 倍。-Ad623 is a integrated single power instrument amplifier, it can in a single power supply (+ 3 v ~+ 12 v) provides the full range of output power, ad623 allows the use of a single gain Settings to gain resistance programming, to get good users the flexibility. There is no external resistance in the condition, ad623 set to units gain　External resistance, ad623 programmable set gain, its gain maximum of 1000 times.
