The MAX6078 precision voltage reference family provides low drift and low noise at a maximum power supply current of only 15µA. Low-frequency noise is less than 12µVP-P (2.5V output voltage option) and the temperature coefficient of the output voltage is less than 10ppm/°C.
The reference output can sink and source up to 3mA of load current and the top grade provides 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. A noise reduction (NR) input pin allows connection of an external capacitor to reduce wideband noise. Available output voltages include 1.25V, 2.048V, 2.5V, 3.0V, 3.3V, 4.096V, and 5.0V.
The tiny, 6-bump WLP and small, 8-pin TDFN-EP packages are suitable for systems where circuit board area is limited. The operating input voltage can range from 2.3V to 5.5V. Operation is specified over the extended industrial temperature range of -55°C to +125°C.
