Features
Maximum range input volts above analog ground clock input Low-Power Mode Sleep Mode converter operated single power supply
General Description
ADC09R03 realized resistive ladder architecture. part operates single supply. 9-Bit designed continuous mode. control signals required begin conversions. Each conversion requires clock-cycles, maximum conversion rate kHz. VALID signal goes high completion conversion, data latched outputs until next assertion VALID. order decrease power consumption, ADC09R03 into low-power modes, sleep low-power. This ultra-low power characteristic makes ADC09R03 ideal portable applications.
