Analog Devices · ADC/DAC - Specialized · TSSOP-16
AD7747ARUZ from Analog Devices, in a TSSOP-16. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | SCL | input | Serial interface clock input that connects to the master clock line and requires a pull-up resistor if one is not already provided in the system. |
| 2 | RDY | output | Logic output whose falling edge indicates that a conversion on the enabled channel(s) has finished and new data is available; leave as an open circuit if not used. |
| 3 | SHLD | passive | Capacitive input for active AC shielding, used to shield the sensor connection and eliminate CIN parasitic capacitance to ground; leave as an open circuit if not used. |
| 4 | TST | unconnected | Test pin that must be left as an open circuit for proper operation. |
| 5 | REFIN(+) | input | Positive differential voltage reference input for the voltage channel (ADC); not used for CDC conversion, and if unused it can be left open or connected to GND. |
| 6 | REFIN(-) | input | Negative differential voltage reference input for the voltage channel (ADC); not used for CDC conversion, and if unused it can be left open or connected to GND. |
| 7 | CIN1(-) | passive | CDC negative capacitive input; the measured capacitance is connected between CIN1(-) and GND, and the pin should be left open if not used. |
| 8 | CIN1(+) | passive | CDC positive capacitive input; the measured capacitance is connected between CIN1(+) and GND, and the pin should be left open if not used. |
| 9 | NC | unconnected | Not connected; this pin should be left as an open circuit. |
| 10 | NC | unconnected | Not connected; this pin should be left as an open circuit. |
| 11 | VIN(+) | power_in | Positive differential voltage input for the voltage channel (ADC), also used to connect an external temperature sensing diode; if not used it can be left open or connected to GND. |
| 12 | VIN(-) | power_in | Negative differential voltage input for the voltage channel (ADC), also used to connect an external temperature sensing diode; if not used it can be left open or connected to GND. |
| 13 | GND | power_in | Ground pin. |
| 14 | VDD | power_in | Power supply voltage pin that should be decoupled to GND with a low impedance capacitor, for example a 10 µF tantalum in combination with a 0.1 µF multilayer ceramic. |
| 15 | NC | unconnected | Not connected; this pin should be left as an open circuit. |
| 16 | SDA | bidirectional | Serial interface bidirectional data pin that connects to the master data line and requires a pull-up resistor if not provided elsewhere in the system. |
