The references are capable of both sinking and sourcing current, and have excellent line and load regulation. Achieve excellent temperature drift (2.5ppm/°C) and high accuracy (0.025%) using proprietary design techniques. These features , bined with very low flicker noise (0.5μVPP/V), make the REF50xx family an excellent choice for use in high-precision data acquisition systems. REF50 family is available in enhanced grade (REF50xx EI), high grade (REF50xx I), and standard grade (REF50xx AI). The reference voltages are offered in 8-pin SOIC and VSSOP packages and are specified from - 40°C to 125°C. For detailed parison across various grades, refer to Table 4-2.
