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.It is also equipped with girdling to
prevent current leak from integration capacitor.
FEATURES
Separate power supplies for analog section and digital section.
Low power dissipation.....................................2mA(typ)
(1mA for A-D conversion and the other 1mA for reset)
Linear error......................................................±0.02%(typ)
Conversion time...............................................526μs/ch(typ)
Built-in system reset.........................................4.45V(typ)
