AD586 is a high-precision 5 V reference that uses ion-implanted buried zener diode and high-stability thin-film resistor laser wafer trimming technology to provide outstanding performance at a low cost.
The AD586 is a high‑precision 5 V voltage reference that uses a proprietary buried Zener diode and laser‑trimmed thin‑film resistors to achieve low noise and low drift. It is offered in several grades (M, B, L, A, S, T) and package types, allowing easy replacement of standard 5 V references.
The document provides full electrical specifications, absolute maximum ratings, pin descriptions, theory of operation, noise performance, turn‑on time, dynamic response, load regulation, temperature performance, and ordering guide information for designers and technicians.
| Output Voltage Accuracy (M grade) | ±2.0 mV |
|---|---|
| Temperature Coefficient (M grade) | 2 ppm/°C max (0°C‑70°C) |
| Output Noise (0.1 Hz‑10 Hz) | 4 µV p‑p |
| Quiescent Current | 2 mA |
| Power Consumption | 30 mW |
The AD586 typically produces less than 4 µV peak‑to‑peak noise over the 0.1 Hz to 10 Hz band.
The turn‑on settling time is about 60 µs to reach 0.01 % accuracy.
The AD586M grade has a maximum deviation of ±2.45 mV from 0°C to 70°C.
