Rainbow Electronics MAX6608 User Manual
General Description
The MAX6607/MAX6608 precision, low-voltage, analog
output temperature sensors are available in 5-pin SC70
and SOT23 packages. The devices have a +1.8V to
+3.6V supply voltage range and 8µA supply current
over the -20°C to +85°C temperature range. Accuracy
is ±0.6°C (typ) from TA= +20°C to +50°C and is
±0.7°C (typ) from TA= 0°C to +70°C.
The MAX6607/MAX6608 output voltage depends on its
die temperature and has a slope of 10mV/°C and an
offset of 500mV at 0°C.

ELECTRICAL CHARACTERISTICS
(V
CC
= +1.8V to +3.6V, CL= 1nF, TA= -20°C to +85°C, typical values are at TA= +25°C, unless otherwise noted.) (Note 1)
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 1: All parameters are measured at TA= +25°C. Specifications over temperature range are guaranteed by design.
Note 2: Not production tested, guaranteed by design.
