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 bypassed to VDD with a 10 nF capacitor). |+| 2 | VDD | power_in | Positive power supply for the analog and digital interface sections. VDD range is 2.3 V to 5.5 V. Also feeds the on-board 2.5 V regulator; decouple with 0.1 uF and 10 uF between VDD and AGND. |+| 3 | CAP/2.5V | passive | Regulated 2.5 V rail for internal digital circuitry, generated from VDD by the on-board regulator 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 master clock input. DDS output frequencies are expressed as a binary fraction of fMCLK; this clock determines output frequency accuracy and phase noise. Max 25 MHz; period tMIN = 40 ns. |+| 6 | SDATA | input | Serial data input. The 16-bit serial data-word is applied to this input (3-wire SPI, MSB first). |+| 7 | SCLK | input | Serial clock input. Data on SDATA is clocked into the AD9833 on each falling edge of SCLK. SCLK period min 25 ns (up to 40 MHz). |+| 8 | FSYNC | input | Active-low frame synchronization / chip-select input. 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 | Analog and digital output of the AD9833. Delivers sine, triangle, or square wave (MSB) with VOUT max ~0.65 V typical. An external load resistor is not required; the device has an on-board 200 ohm resistor to AGND. |++## 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-REEL`+- `AD9833BRMZ-REEL7`+- `AD9833BRMZ-REELWBRMZ`+- `AD9833BRMZ-REELWBRMZ-REEL`+- `AD9833BRMZ-REELWBRMZ-REEL7`++## CAD (KiCad official)++- Symbol: `AD9833BRMZ-REEL`+- 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/8588886123355779072) (21 pp, sha256 `426eb7a26ea9dc0d`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
