The specialized chip BA234 is an integrated circuit chip specifically designed for conductivity signal processing. Combined with metal or ink electrodes, it can be used to measure the conductivity of a solution. This conductivity signal processing chip integrates functions such as probe driving, conductivity signal acquisition, amplification, filtering, temperature compensation, etc. into one, which can greatly reduce the volume of user circuit systems; The chip adopts advanced circuit design and manufacturing processes, which can achieve high-precision conductivity measurement and high reliability; The core can adapt to different conductivity ranges, perform measurements in various application scenarios, and is not easily affected by environmental factors, with stable performance. The chip has a simple interface circuit and digital signal output, which can be easily connected to computers or other digital systems to achieve automated measurement and control.
