The AD588 is a high precision voltage reference that features low drift (1.5 ppm/°C), low initial error (1 mV), pin programmable output (+10 V, +5 V, +65 V tracking, -5 V, -10 V), flexible output force and sense terminals, high impedance ground sense, machine insertable DIP packaging and MIL-STD-883 compliant versions.
The AD588 is a monolithic voltage reference featuring low initial error (1 mV) and low temperature drift (1.5 ppm/°C). It utilizes a proprietary ion-implanted buried Zener diode and laser-wafer-drift trimming to ensure absolute accuracy suitable for 12-bit systems.
The device offers pin-programmable output voltages including +10 V, +5 V, -5 V, and -10 V configurations. It includes three additional amplifiers configured for Kelvin connections or driving high current loads, available in CERDIP packages with industrial (A, B) or commercial (J, K) temperature ranges.
| Initial Error | 1 mV (AD588BQ/KQ) |
|---|---|
| Temperature Drift | 1.5 ppm/°C |
| Output Voltage Error (+10 V) | +3 to +1 mV |
| Supply Current | 6 mA (Typical) |
Yes, its low initial error allows it to provide known voltage for system calibration in applications requiring 12-bit absolute accuracy.
The device can dissipate up to 300 mW.
The output noise is typically 6 µV peak-to-peak.
