The AD586 is a high-precision 5V voltage reference that utilizes a proprietary ion-implanted buried Zener diode and laser-trimmed high stability thin-film resistors, providing outstanding performance at a low cost. The AD586 offers much higher performance than most other 5V voltage references.
The AD586 series from Analog Devices provides a monolithic 5 V voltage reference using a proprietary buried Zener diode and laser‑trimmed thin‑film resistors. It offers very low noise (typically 4 µV p‑p over 0.1‑10 Hz) and excellent temperature stability, with grades ranging from ±2 ppm/°C to ±10 ppm/°C.
The device is available in 8‑lead PDIP, SOIC and CERDIP packages and can source or sink up to 10 mA. No external components are required for basic operation, while an optional fine‑trim pin allows precise output adjustment. The datasheet includes detailed specifications, pin descriptions, noise performance, turn‑on time and absolute maximum ratings.
| Power Consumption | 30 mW |
|---|---|
| Output Noise (0.1‑10 Hz) | 4 µV p‑p |
| Spectral Density (100 Hz) | 100 nV/V·Hz |
| Long‑Term Stability | 15 ppm/1000 hr |
| Operating Temperature Range (grade‑dependent) | ‑40 °C to +85 °C (A/B grades), 0 °C to 70 °C (M/L grades), ‑55 °C to +125 °C (S/T grades) |
The AD586 typically produces 4 µV peak‑to‑peak noise over the 0.1 Hz to 10 Hz band.
The device requires less than 3 mA quiescent current from a 12 V or 15 V supply.
The AD586M grade guarantees a maximum deviation of +2.45 mV from 5.000 V between 0 °C and 70 °C.
