Description
M62303FP is a double integration type A/D converter support system, and is a semiconductor integrated circuit which
can work as A/D converter of 14 bits or more by being used with MCU and by inputting SI, SCK1, CS, and CONTIN.
High precision A/D translation system can be realized without using high precision external parts by proofreading A/D
acquired values with two or more known conversion values such as reference voltage, grounding (zero) voltage and so
forth.
Features
• High precision (14 bits or more) double integration type A/D converter
• Positive/negative constant voltage source built-in (+6.3 V, –6.0 V Typ)
• Positive/negative constant current source built-in (Isource = 2 mA, Isink = 0.2 mA Max)
• Independent 2ch operational amplifier built-in
• System reset built-in (4.5 V Typ)
Application
High precision control systems, such as temperature control and speed control
