MAX6079

Low-Noise Precision Ceramic Voltage Reference

Ceramic Package Reference Offers Lowest Drift Over Time, Temperature and Humidity


Please check latest availability status for a specific part variant.

Description

The MAX6079 offers a very low noise and low-drift voltage reference in a small 8-pin Ceramic package. The device provides a 1/f noise voltage of only 4.8μVP-P at an output voltage of 2.5V, with a temperature drift of 6ppm/°C (max). The device consumes 160μA of supply current and can sink and source up to 10mA of load current. The low-drift and low-noise specifications enable enhanced system accuracy, making these devices ideal for high-precision industrial applications. The MAX6079 offers a noise filter option for wideband applications.

The MAX6079 is available in an 8-pin ceramic package and is specified over the extended industrial temperature range of ‑40°C to +125°C.
