AGND
Ground Reference Point for Analog Circuitry.
20
RDY
Logic Output. Used as a status output in both conversion mode and calibration mode. In
conversion mode, a falling edge on this output indicates that either any channel or all
channels have unread data available, according to the RDYFN bit in the I/O port register.
In calibration mode, a falling edge on this output indicates that calibration is complete
(see the Digital Interface Description section for details).
21
DOUT
Serial Data Output. Serial data is read from the output shift register on the part. This
output shift register can contain information from any AD7739 register, depending on
the address bits of the communications register.
22
DIN
Serial Data Input (Schmitt Triggered). Serial data is written to the input shift register on
the part. Data from this input shift register is transferred to any AD7739 register,
depending on the address bits of the communications register.
23
DVDD
Digital Supply Voltage, 3 V or 5 V Nominal.
24
DGND
Ground Reference Point for Digital Circuitry.
