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.
