[AK8448]
… Reference Voltage Reference Voltage Generation Circuit
Circuit to generate internal Clamp level VCLP, Analog Common Level VCOM, ADC Reference
Voltages VRP & VRN and DAC Reference Voltages DAREFP & DAREFN.
… Timing Control
Timing Generating Circuit
Digital circuit to generate internal timing pulses from those input clocks, ADCK, SHR, SHD and
CLPB.
ADCK is a clock which is used for ADC operation and for operation of ADC Output Data Control
part.
SHR is a timing pulse which is used to sample Reference level of Sensor signal.
SHD is a timing pulse which is used to sample Data level of Sensor signal.
CLPB is a timing pulse to show Clamp period.
… Serial I/F Control
Serial Register Interface Circuit
A 4-Wire Interface to set values at the Control registers.
Control registers also can be read out.
By assigning specific address to individual devices by chip enable pins CE0 and CE1, up to 4.
AK8448 devices can be connected on the same, 4-wires.
