@@ -0,0 +1,52 @@+# ADR4525++**Analog Devices** · Voltage reference · SOIC-8++Series voltage reference that holds 2.5 V to 0.02% initial accuracy with a 2 ppm/C temperature drift, in a SOIC-8. Low output noise and high stability suit it to driving the reference input of a precision ADC or DAC, where the converter's accuracy is capped by the reference. It takes any supply from a few hundred mV above the output up to 15 V. The 2.5 V member of the ADR45xx family (2.048 V through 5.0 V).++## Pinout++| Pin | Name | Type | Function |+|---|---|---|---|+| 1 | NIC | unconnected | Not Internally Connected. This pin is not connected internally; may be tied to any potential or left floating. |+| 2 | VIN | power_in | Input Voltage Connection. Operating range 3 V to 15 V. Decouple with a 0.1 µF ceramic capacitor to GND close to the pin. |+| 3 | NIC | unconnected | Not Internally Connected. This pin is not connected internally. |+| 4 | GND | power_in | Ground return for the device. Connect to the system analog ground with a low-impedance path. |+| 5 | NIC | unconnected | Not Internally Connected. This pin is not connected internally. |+| 6 | VOUT | power_out | Reference Output Voltage, nominal 2.500 V. Sources up to +10 mA and sinks up to -10 mA. Recommended output capacitor 1 µF (load capacitance range 1 µF to 100 µF). |+| 7 | NIC | unconnected | Not Internally Connected. This pin is not connected internally. |+| 8 | DNC | unconnected | Do Not Connect. Do not connect to this pin, do not tie to any potential and do not route a trace to it. |++## Key specifications++| Parameter | Value |+|---|---|+| Type | Series (bandgap) voltage reference |+| Output | 2.5 V |+| Initial accuracy | +/-0.02% (A grade) |+| Temp coefficient | 2 ppm/C (max) |+| Output noise | 1.25 uV p-p (0.1-10 Hz) |+| Supply | Output + 0.3 V to 15 V |+| Package | SOIC-8 |++## Ordering variants++- `ADR4525ARMZ (MSOP-8)`+- `ADR4525BRZ (SOIC-8)`+- `ADR4525ARZ (SOIC-8)`++## CAD (KiCad official)++- Symbol: `Reference_Voltage:ADR4525 (KiCad official)`+- 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://www.analog.com/media/en/technical-documentation/data-sheets/ADR4520_4525_4530_4533_4540_4550.pdf) (41 pp, sha256 `de2dca59e24477c2`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
