# AD7980ARMZ

**Analog Devices** · Analog To Digital Converters (ADCs) · MSOP-10

AD7980ARMZ from Analog Devices, in a MSOP-10. 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 | REF | input | Reference input voltage; the REF range is from 2.4 V to 5.1 V, referred to GND, and the pin should be decoupled closely with a 10 µF capacitor. |
| 2 | VDD | power_in | Power supply, from which the ADC operates as a single-supply device. |
| 3 | IN+ | input | Analog input referred to IN−, where the voltage difference between IN+ and IN− is 0 V to VREF. |
| 4 | IN- | input | Analog input ground sense, to be connected to the analog ground plane or to a remote sense ground. |
| 5 | GND | power_in | Power supply ground. |
| 6 | CNV | input | Convert input whose leading edge initiates conversions and selects chain or CS interface mode; in CS mode it enables SDO when low. |
| 7 | SDO | output | Serial data output on which the conversion result is output, synchronized to SCK. |
| 8 | SCK | input | Serial data clock input by which the conversion result is shifted out when the device is selected. |
| 9 | SDI | input | Serial data input that selects the interface mode: chain mode if low at the CNV rising edge, CS mode if high. |
| 10 | VIO | power_in | Input/output interface digital power, nominally at the same supply as the host interface (1.8 V, 2.5 V, 3 V, or 5 V). |
