MAX6078A/MAX6078B
EVALUATION KIT AVAILABLE
Low-Power, Low-Drift,
Low-Noise Voltage Reference
General Description
The MAX6078 precision voltage reference family provides
low drift and low noise at a maximum power supply cur-
rent 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 connection of an external capacitor
to reduce wideband noise. Available output voltages in-
clude 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 pack-
ages 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 industri-
al temperature range of -55°C to +125°C.

Note that a “+”, “#”, or “-” in the package code indicates RoHS status only. Package drawings may show a different
suffix character, but the drawing pertains to the package regardless of RoHS status.
Package thermal resistances were obtained using the method described in JEDEC specification JESD51-7, using a
four-layer board. For detailed information on package thermal considerations, refer to www.maximintegrated.com/
