MITSUBISHI M62301SP,FP 10~12-BIT 4CH INTEGRATING A-D CONVERTER DESCRIPTION M62301 semiconductor integrated circuit forms an integrating A-D converter,being connected to a microcomputer unit.By using selection signals and counter clock signals from the unit,a 10~12-bit A-D converter can be created at a low cost. The integration time and resolution can be set at the user‘s option by changing external parameters.In addition,the built-in circuit offset,delay time and temperature fluctuation are adjustable,enabling a wide range of applications. M62301 has a 3 input decoder circuit,high-precision reference voltage(1.22V)generator,current supply and comparator for integration,and voltage-monitoring reset circuit for a 5V power supply.
