# AD5541ARZ

**Analog Devices** · Digital To Analog Converters (DACs) · SOIC-8

AD5541ARZ from Analog Devices, in a SOIC-8. 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. |

## CAD (KiCad official)

- Symbol: `AD5541ARZ`
- Footprint: `Package_SO:SOIC-8_3.9x4.9mm_P1.27mm`
- 3D model: SOIC-8 (KiCad packages3D, STEP)
- 3D model files: `ad5541arz-etched.step` / `ad5541arz-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `ad5541arz.step` / `ad5541arz.glb` are the bare package body.
