9 / 32 page Data Sheet AD7739 Rev. A | Page 9 of 32 Pin No. Mnemonic Description 19 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. |
