MAX8069 DS
General Description
The MAX8069 is a 1.2V temperature-compensated volt-
age reference. It uses the bandgap principle to achieve
excellent stability and low noise at reverse currents down
to 60A. The MAX8069 also features excellent stability,
freedom from oscillation. The MAX8069 is a functional
alternative to Maxim's ICL8069 with an identical pinout.

ABSOLUTE MAXIMUM RATINGS
ELECTRICAL CHARACTERISTICS
(T
A
= +25C, unless otherwise noted.) (Note 2)
Stresses beyond those listed under "Absolute Maximum Ratings" may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.
Note 2: If circuit strays in excess of 200pF are anticipated, a 4.7F shunt capacitor will ensure stability under all operating condi-
tions.
Reverse Voltage ..............................................................(Note 1)
Forward Current ..................................................................10mA
Reverse Current ..................................................................10mA
Power Dissipation.......Limited by Max Forward/Reverse Current
Storage Temperature Range .............................-65C to +150C
Operating Temperature Range
MAX8069CCZQ ...................................................0C to +70C
MAX8069CEZQ, MAX8069ESA ........................-40C to +85C
Lead Temperature (soldering, 10s) .................................+300C
Note 1: In normal use, the reverse voltage cannot exceed the reference voltage. However, when plugging units into a powered-up
test fixture, an instantaneous voltage equal to the compliance of the test circuit will be seen. This should not exceed 20V.
