Analog Devices / Maxim Integrated MAX6078 Precision Voltage Reference
Analog Devices MAX6078 Precision Voltage Reference provides low drift and low noise at a maximum power supply current of only 15μA. Low-frequency noise is less than 12μVPP (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 the 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.
