MAX873 Datasheet Low-power / Low-drift / +2.5v/+5v/+10v Precision Voltage References

Manufacturer: Maxim Integrated (now Analog Devices)

Overview: MAX873/MAX875/MAX876 19-0038; Rev 3; 6/07 Low-Power, Low-Drift, +2.

General Description

The MAX873/MAX875/MAX876 precision 2.5V, 5V, and 10V references offer excellent accuracy and very low power consumption.

Extremely low temperature drift bined with excellent line and load regulation permit stable operation over a wide range of electrical and environmental conditions.

Operation for the MAX873 is guaranteed with a +4.5V supply, making the part ideal in systems running from a +5V ±10% supply.

Key Features

  • MAX873/MAX875/MAX876 +2.5V/+5V/+10V Outputs ±1.5mV/±2.0mV/±3.0mV (max) Initial Accuracy.
  • 7ppm/°C (max) Temperature Coefficient.
  • 450µA (max) Quiescent Current.
  • Low Noise: 3.8µVP-P (typ at 2.5V).
  • Sources 10mA, Sinks 2mA.
  • 15ppm/mA Load Regulation (max).
  • 4ppm/V Line Regulation (max).
  • Wide Supply Voltage Range, +4.5V to +18V (MAX873).
  • TEMP Output Proportional to Temperature.
