Low-noise, high-precision series voltage references

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 operate with an input voltage from 2.8V to 5.5V. The MAX6070/MAX6071 consume 150µA of supply current and can sink and source up to 10mA of load current. The MAX6070/MAX6071 provide an initial accuracy of 0.04%. 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 MAX6070/MAX6071 provide output voltages of 1.25V, 1.8V, 2.048V, 2.5V, 3.0V, 3.3V, 4.096V, and 5.0V. The devices are available in a 6-pin SOT23 package and specified over the extended industrial temperature range of -40°C to +125°C.
