Low-Noise, High-Precision Series Voltage References

Highest Performance SOT23 Voltage References with 6ppm/°C Maximum Temperature Coefficient

Please check latest availability status for a specific part variant.


The MAX6070/MAX6071 offer a very low noise and low-drift voltage reference in a small 6-pin SOT23 package. These devices provide 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 devices consume 150µA 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 MAX6070 offers a noise filter option for wideband applications.

The devices are available in a 6-pin SOT23 package and specified over the extended industrial temperature range of -40°C to +125°C. The 2.5V options are also available in a 6-bump 0.78mm x 1.41mm wafer-level package (WLP).
