MAX6607/MAX6608 19-2040 Rev 1 6/01 Low-Voltage Analog Temperature Sensors in SC70 and SOT23 Packages General Description Features The MAX6607/MAX6608 precision, low-voltage, analog Operate Down to 1.8V Supply output temperature sensors are available in 5-pin SC70 Low Current Consumption (15A max) and SOT23 packages. The devices have a +1.8V to +3.6V supply voltage range and 8A supply current Small SC70 and SOT23 Packages over the -20C to +85C temperature range. Accuracy 2.0C (max) Accuracy from +20C to +50C is 0.6C (typ) from T = +20C to +50C and is A 0.7C (typ) from T = 0C to +70C. A Optimized to Drive Capacitive Loads Up to The MAX6607/MAX6608 output voltage depends on its 1000pF die temperature and has a slope of 10mV/C and an offset of 500mV at 0C.
