MAX676 - Precision Voltage References

General Description

The MAX676/MAX677/MAX678 precision +4.096V, +5V, and +10V voltage references feature a factory-programmed on-chip ROM that calibrates each reference at specific temperatures, and reduces the temperature drift to less than 1ppm/°C over temperature

the lowest in the industry.

Key Features

  • o Lowest Temperature Drift: 1ppm/°C Max Over -40°C to +85°C 1.5ppm/°C Max Over -55°C to +125°C o 0.02% Initial Accuracy o 3ppm/mA Max Load Regulation o 30ppm/V Max Line Regulation o 4.096V Reference Operates from 5V ±5% Supply o Available in Surface-Mount Package ______________Ordering Information PART TEMP.

19-0200; Rev. 1; 11/94 MAX676/MAX677/MAX678 Calibrated, Low-Drift, +4.096V/+5V/+10V Precision Voltage References _______________General Description The MAX676/MAX677/MAX678 precision +4.096V, +5V, and +10V voltage references feature a factory-programmed on-chip ROM that calibrates each reference at specific temperatures, and reduces the temperature drift to less than 1ppm/°C over temperature—the lowest in the industry. The MAX676/MAX677/MAX678 have excellent line and load regulation: 30ppm/V and 3ppm/mA, respectively. Load regulation specifications are guaranteed for source currents up to 5mA and sink currents up to 500µA. The 4.096V MAX676 operates from a supply voltage as low as 4.75V, making it an ideal reference for single 5V, high resolution ADCs.
