Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.++## Pinout++| Pin | Name | Type | Function |+|---|---|---|---|+| 1 | VDD | power_in | Positive power supply. Should be decoupled with a 0.1 µF ceramic capacitor and a 10 µF capacitor. Range 2.7 V to 5.5 V (single supply) or +2.5 V to +2.75 V (dual supply). |+| 2 | A | passive | RDAC A terminal. Terminal voltage must be between VSS ≤ VA ≤ VDD. Nominal end-to-end resistance to W is 100 kΩ. |+| 3 | W | passive | RDAC wiper terminal. Terminal voltage must be between VSS ≤ VW ≤ VDD. Wiper position is set via the I2C interface with 1024-step (10-bit) resolution. |+| 4 | VSS | power_in | Negative power supply. Connect to 0 V for single-supply operation, or to -2.5 V to -2.75 V for dual-supply operation. Should be decoupled with a 0.1 µF ceramic capacitor and a 10 µF capacitor. |+| 5 | EXT_CAP | passive | External capacitor pin. A 1 µF capacitor with voltage rating ≥7 V must be connected between EXT_CAP and VSS. Required for 50-TP programming charge-pump operation. |+| 6 | GND | power_in | Ground pin, logic ground reference. |+| 7 | RESET | input | Hardware reset input, active low. Refreshes the RDAC register with the contents of the 50-TP memory location. On power-up, defaults to midscale until the first 50-TP memory location is programmed. Tie to VDD if unused. |+| 8 | SDA | bidirectional | I2C serial data line. Bidirectional open-drain data line used with SCL to transfer the 16-bit input shift register. Requires an external pull-up resistor to VDD (e.g. 2.2 kΩ). |+| 9 | SCL | input | I2C serial clock input. Used with SDA to shift in/out the 16-bit input shift register. Supports standard-mode (100 kHz) and fast-mode (400 kHz). |+| 10 | ADDR | input | Tri-state address input. Sets the two LSBs (A1, A0) of the 7-bit I2C slave address (see Table 11). Enables up to three parts on the same I2C bus. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Analog Devices |+| Package | MSOP-10 |+| Category | ADC/DAC/Data Conversion |+| Pins | 10 |++## Ordering variants++Same part, different packaging or reel option.++- `AD5272BRMZ-100`+- `AD5272BRMZ-100-RL7`+- `AD5272BRMZ-100BCPZ-100`++## CAD (KiCad official)++- Symbol: `AD5272BRMZ-100`+- Footprint: `Package_SO:MSOP-10_3x3mm_P0.5mm`+- 3D model: MSOP-10 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Analog Devices datasheet](https://jlcpcb.com/api/file/downloadByFileSystemAccessId/8588883518222962688) (28 pp, sha256 `e7d7afbbd3932e2d`, retrieved 2026-08-17, tier: lcsc)+- **Datasheet language:** Chinese.
