title: [Design of CA-1680 biochemical analyzer].
abstract: The paper provides the design idea structure of key parts software and hardware of microprocessor of CA-1680 Biochemical Analyzer. The instrument uses the specific flow cell high properties photodiode and programmable amplifier. The 16 bit programmable A/D conversion is completed with V/F convertor and programmable counter. Logarithm conversion is completed with software. On Using these methods, the instrument has not only simpler circuit, better reliability, but also the characteristics of accuracy, precision and widely linearity.
