MAX6605 19-1840 Rev 3 12/09 Low-Power Analog Temperature Sensor in SC70 Package General Description Features The MAX6605 precision, low-power, analog output tem- Low Current Consumption (10A max) perature sensor is available in a 5-pin SC70 package. Small SC70 Package The device has a +2.7V to +5.5V supply voltage range Accurate (0.75C at T = +25C) and 10A supply current over the -55C to +125C tem- A perature range. For the -40C to +105C temperature Optimized to Drive Large Capacitive Loads range, the supply voltage can go as low as +2.4V. Accuracy is 0.75C at T = +25C and 3C from 0C A Ordering Information to +70C. PART TEMP RANGE PIN-PACKAGE The MAX6605 output voltage is dependent on its die temperature and has a slope of 11.9mV/C and an off- MAX6605MXK-T -55C to +125C 5 SC70-5 set of 744mV at 0C. The output typically shows only MAX6605MXK+T -55C to +125C 5 SC70-5 +0.4C of nonlinearity over the -20C to +85C temper- MAX6605MXK/V+T -40C to +85C 5 SC70-5 ature range. +Denotes a lead(Pb)-free/RoHS-compliant package.
