MAX6072

High-Precision, Dual-Output Series

Voltage Reference

General Description

The MAX6072 is a dual-output precision series voltage

• B-grade: 8ppm/°C (max)

REF

2ppm (peak-to-peak). Each output can source and sink

10mA and has an independent sense line. This product

has a temperature drift of 6ppm/°C (max) over the ambi-

ent temperature range of -40°C to +125°C and an initial

accuracy of 0.04%. Three pairs of output voltages are

available: 5V/2.5V, 4.096V/2.048V, and 2.5V/1.25V. The

product operates with an input voltage range of 2.8V to

5.5V and has sufficient headroom for the highest voltage.

It consumes a mere 150µA (typ) of quiescent supply cur-

rent per reference. The dual voltage outputs make this

device ideal for precision ADC applications where the
