MAX6070/MAX6071 Low-Noise, High-Precision Voltage

The MAX6070 and MAX6071 from Maxim 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 4.8 μVPP at an output voltage of 2.5 V, with a temperature drift of 6 ppm/°C (max). The devices operate with an input voltage from 2.8 V to 5.5 V. The MAX6070 and MAX6071 consume 150 µA of supply current and can sink and source up to 10 mA of load current. The MAX6070 and 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 and MAX6071 provide output voltages of 1.25 V, 1.8 V, 2.048 V, 2.5 V, 3.0 V, 3.3 V, 4.096 V, and 5.0 V. The devices are available in a 6-pin SOT23 package and specified over the extended industrial temperature range of -40°C to +125°C.
