[AK4182]
Digital I/F
The digital I/O of AK4182 can operate from 1.5V IOVDD. This allows connecting the low –voltage microprocessor. The full
scale level of digital I/O voltage is specified IOVDD.

Control Command
The control command, 8 bits, provided to the AK4182 via DIN is shown in the following table. This command includes start bit,
channel selection, resolution, measurement configuration, and power-down mode. The AK4182 latches the serial command at the
rising edge of DCLK. Refer to the detailed information regarding the bit order, function, the status of driver switch, ADC input,
reference voltage as shown in

Function
Start Bit. This bit must be “H” because the AK4182 initiates the command recognition
Channel Selection Bits. Analog inputs to the A/D converter and the activated driver switches are
selected. Please see the following table for the detail.
