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 | COMP | passive | DAC Bias Pin. Used for decoupling the DAC bias voltage; typically decoupled with a 10 nF capacitor to VDD. |+| 2 | VDD | power_in | Positive Power Supply for the analog and digital interface sections (2.3 V to 5.5 V). Also supplies the on-board 2.5 V regulator. Should be decoupled with 0.1 µF and 10 µF capacitors to AGND. |+| 3 | CAP/2.5V | passive | Regulator output/bypass. The digital circuitry operates from 2.5 V generated by an on-board regulator from VDD (when VDD > 2.7 V). Requires a ~100 nF decoupling capacitor from CAP/2.5V to DGND. If VDD ≤ 2.7 V, tie CAP/2.5V directly to VDD. |+| 4 | DGND | power_in | Digital Ground return. |+| 5 | MCLK | input | Digital Clock Input. DDS output frequencies are expressed as a binary fraction of MCLK; determines output frequency accuracy and phase noise. Max 25 MHz (t1 ≥ 40 ns period). |+| 6 | SDATA | input | Serial Data Input. 16-bit serial data-word applied to this input; clocked in on falling edge of SCLK. |+| 7 | SCLK | input | Serial Clock Input. Data is clocked into the AD9833 on each falling edge of SCLK. Rates up to 40 MHz. |+| 8 | FSYNC | input | Active Low Control Input (frame sync). When FSYNC is taken low, the internal logic is informed that a new 16-bit word is being loaded into the device. |+| 9 | AGND | power_in | Analog Ground return. |+| 10 | VOUT | output | Voltage Output. Analog and digital output of the AD9833 (sine, triangle, or square wave). An external load resistor is not required because the device has an on-board 200 Ω resistor. VOUT max ~0.65 V, min ~38 mV. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Analog Devices |+| Package | MSOP-10 |+| Category | Data Acquisition |+| Pins | 10 |++## Ordering variants++Same part, different packaging or reel option.++- `AD9833BRMZ`+- `AD9833BRMZ-REEL`+- `AD9833BRMZWBRMZ`+- `AD9833BRMZWBRMZ-REEL`++## CAD (KiCad official)++- Symbol: `AD9833BRMZ`+- 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/8588927806441476096) (21 pp, sha256 `426eb7a26ea9dc0d`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
