10~12-BIT 4CH INTEGRATING A-D CONVERTER
2.4-channel 12-bit A-D converter system
Separate power supplies to analog section and digital section,
analog input voltage range mode wider up to V
DD
,external
reference voltage for integration.
Because separate power supplies are provided for the
analog are digital sections,the M62301 has two supply
voltage Vcc and V
DD
,enabling a wide analog input voltage
range V
IA
.The upper limit of the range is required to be no
more than the difference between Vcc-2.5V as well as
V
DD
,therefore,the analog input voltage range in this
application is 0V to 5V.
