The AD587 is a high precision 10V voltage reference produced by AD. It uses proprietary ion-implanted buried Zener diodes and laser wafer trimming technology, and has outstanding performance and low price.
The AD587 is a monolithic voltage reference utilizing a proprietary ion-implanted buried Zener diode and laser-trimmed resistors to provide high accuracy and stability. It is designed for use with high-resolution DACs and ADCs, offering performance superior to standard on-chip references. The device is available in various grades (J, K, U) and packages, including CERDIP, SOIC, and PDIP.
| Output Voltage (U Grade) | 10.000 V + 5 mV |
|---|---|
| Temperature Coefficient (U Grade) | 5 ppm/°C maximum |
| Quiescent Current | 4 mA maximum |
| Output Noise (0.1 Hz to 10 Hz) | 4 µV p-p |
| Operating Temperature (U Grade) | -55°C to +125°C |
| Power Dissipation | 30 mW |
The AD587U guarantees a maximum total error of +14 mV between -55°C and +125°C.
Noise can be further reduced by adding an external capacitor to the NOISE REDUCTION pin (Pin 8).
Yes, it uses an industry-standard pinout, allowing for instant upgrades of systems using other 10 V references.
