SERIAL MODE

The AD7386 offers an option to have a 1-wire or a 2-wire
configuration for serial communication. Click the Control
Logic block to configure this option.
Serial 2-Wire Mode
Configure 2-wire mode by setting the SDO bit in the
CONFIGURATION2 register (Address 0x02) to 0. In 2-wire
mode, the conversion result for ADC A is output on the SDOA
pin, and the conversion result for ADC B is output on the
SDOB/ ALERT pin.
Serial 1-Wire Mode
In applications where slower throughput rates are allowed, or
normal average oversampling is used, the serial interface can
operate in 1-wire mode. In 1-wire mode, the conversion results
from ADC A and ADC B are output on the serial output,
SDOA. Additional SCLK cycles are required to propagate all
data. ADC A data is output first, followed by ADC B conversion
results.
