AD7687BRMZ 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 with a range of 0.5 V to VDD referred to GND; place a 10 μF decoupling capacitor as close to the pin as possible. |
| 2 | VDD | power_in | Power supply, single-supply operation from 2.3 V to 5.5 V. |
| 3 | IN+ | input | Differential positive analog input; the differential input range is ±VREF. |
| 4 | IN- | input | Differential negative analog input; the differential input range is ±VREF. |
| 5 | GND | power_in | Power supply ground, the reference for REF and the analog and digital inputs. |
| 6 | CNV | input | Convert input whose leading edge starts a conversion and selects chain or CS mode (set by SDI); in CS mode it enables SDO when low, and in chain mode data is read while it is high. |
| 7 | SDO | output | Serial data output carrying the conversion result, synchronized to SCK; it also acts as the BUSY indicator when that feature is enabled. |
| 8 | SCK | input | Serial data clock that shifts data out on SDO when data is valid; in chain mode its level at the CNV rising edge enables (high) or disables (low) the BUSY indicator. |
| 9 | SDI | input | Serial data input that selects the interface mode at the CNV rising edge: low selects chain mode (daisy-chain data input, output on SDO after 16 SCK cycles), high selects CS mode. |
| 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). |
