MAXIM MAX6605 Technical data
For pricing, delivery, and ordering information, please contact Maxim Direct at 1-888-629-4642,
or visit Maxim’s website at www.maxim-ic.com.
General Description
The MAX6605 precision, low-power, analog output temperature sensor is available in a 5-pin SC70 package.
The device has a +2.7V to +5.5V supply voltage range
and 10µA supply current over the -55°C to +125°C temperature range. For the -40°C to +105°C temperature
range, the supply voltage can go as low as +2.4V.
Accuracy is ±0.75°C at TA= +25°C and ±3°C from 0°C
to +70°C.
The MAX6605 output voltage is dependent on its die
temperature and has a slope of 11.9mV/°C and an offset of 744mV at 0°C. The output typically shows only
+0.4°C of nonlinearity over the -20°C to +85°C temperature range.

ELECTRICAL CHARACTERISTICS
(V
CC
= +2.7V to +5.5V, CL= 1nF, TA= -55°C to +125°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: Error (expressed in °C) is defined as the difference between the calculated and measured values of output voltage.
Guaranteed by design to 5 sigma.
