General Description
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.
