REF5020AIDR General Description

The REF50xx is a family of low-noise, low-drift, very high precision voltage references. These references are capable of both sinking and sourcing current, and have excellent line and load regulation.

Excellent temperature drift (3 ppm/°C) and high accuracy (0.05%) are achieved using proprietary design techniques. These features, combined with very low noise, make the REF50xx family an excellent choice for use in high-precision data acquisition systems.

Each reference voltage is available in both high grade (REF50xxIDGK and REF50xxID) and standard grade (REF50xxAIDGK and REF50xxAID). The reference voltages are offered in 8-pin VSSOP and SOIC packages, and are specified from –40°C to 125°C.

Key Features

Low temperature drift:
- High-grade: 3 ppm/°C (maximum)
- Standard-grade: 8 ppm/°C (maximum)
High accuracy:
- High-grade: 0.05% (maximum)
- Standard-grade: 0.1% (maximum)
Low noise: 3 µV PP/V
Excellent long-term stability:
- 22 ppm after first 1000 hours (SOIC-8)
- 50 ppm after first 1000 hours (VSSOP-8)
High-output current: ±10 mA
Temperature range: –40°C to 125°C
