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 | VOUT | output | Analog output voltage from the DAC. Unbuffered output; range 0 V to VREF in unipolar operation. Capable of driving 60 kΩ loads directly (DAC output impedance typ. 6.25 kΩ). |+| 2 | AGND | power_in | Analog ground reference point for the DAC's analog circuitry. Tie to system analog ground (AGND = DGND = 0 V). |+| 3 | REF | input | Voltage reference input for the DAC. Connect to an external 2.5 V reference; reference input range 2.0 V to VDD. Reference input resistance is code-dependent (min ~9 kΩ, typically at code 0x8555). |+| 4 | CS | input | Active-low chip select. Frames the serial data input transfer. Logic input compatible with SPI/QSPI/MICROWIRE. |+| 5 | SCLK | input | Serial clock input. Data is clocked into the input register on the rising edge of SCLK. Maximum 25 MHz; duty cycle must be between 40% and 60%. |+| 6 | DIN | input | Serial data input. Accepts 16-bit words; data is clocked into the input register MSB first on the rising edge of SCLK. |+| 7 | DGND | power_in | Digital ground reference point for digital circuitry. Tie to system digital ground (AGND = DGND = 0 V). |+| 8 | VDD | power_in | Analog supply voltage, 2.7 V to 5.5 V (nominal 5 V ±10%). Typical IDD = 125 µA; power dissipation typ. 0.625 mW at 5 V. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Analog Devices |+| Package | SOIC-8 |+| Category | ADC/DAC/Data Conversion |+| Pins | 8 |++## Ordering variants++Same part, different packaging or reel option.++- `AD5541ARZ`+- `AD5541ARZAR-REEL7`+- `AD5541ARZ-REEL7`+- `AD5541ARZBR`+- `AD5541ARZBRZ`+- `AD5541ARZBRZ-REEL`+- `AD5541ARZCR`+- `AD5541ARZCRZ`+- `AD5541ARZCRZ-REEL7`+- `AD5541ARZJR`+- `AD5541ARZJR-REEL7`+- `AD5541ARZJRZ`+- `AD5541ARZJRZ-REEL7`+- `AD5541ARZLR`+- `AD5541ARZLR-REEL7`+- `AD5541ARZLRZ`+- `AD5541ARZLRZ-REEL7`+- `AD5542AR`+- `AD5542AR-REEL7`+- `AD5542ARZ`+- `AD5542ARZ-REEL7`+- `AD5542BR`+- `AD5542BRZ`+- `AD5542BRZ-REEL7`+- `AD5542CR`+- `AD5542CR-REEL7`+- `AD5542CRZ`+- `AD5542CRZ-REEL7`+- `AD5542JR`+- `AD5542JR-REEL7`+- `AD5542JRZ`+- `AD5542JRZ-REEL7`+- `AD5542LR`+- `AD5542LRZ`++## CAD (KiCad official)++- Symbol: `AD5541ARZ`+- Footprint: `Package_SO:SOIC-8_3.9x4.9mm_P1.27mm`+- 3D model: SOIC-8 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Analog Devices datasheet](https://jlcpcb.com/api/file/downloadByFileSystemAccessId/8590008812985094144) (20 pp, sha256 `6a9cdf0db0bc1b51`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
