MAX6079
Low-Noise Precision Ceramic Voltage Reference
General 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.

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional operation
of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum
rating conditions for extended periods may affect device reliability.
