DS600U+T&R Analog Devices

DS600 0.5 Accurate Analog-Output Temperature Sensor GENERAL DESCRIPTION BENEFITS AND FEATURES The DS600 is a 0.5C accurate analog-output Accurate Temperature Monitoring Easily Added temperature sensor. This accuracy is valid over its to Any System entire operating voltage range of 2.7V to 5.5V and o 0.5C Accuracy (-20C to +100C) the wide temperature range of -20C to +100C. The o 0.75C Accuracy Over Entire Temperature DS600 can also act as a thermostat, with user- Range of -40C to +125C programmable trip points. A shutdown mode enables o 6.45mV/C Output Gain with 509mV Offset at 0C the DS600 to be placed in a low-power standby state. o Requires No External Components The DS600 is available in an 8-pin SOP package. o User-Programmable Thermostat Function Used In a Wide Variety of Applications o Power Supply Range (2.7V to 5.5V) Reacts Quickly to Temperature Shifts APPLICATIONS o Exposed Pad 8-Pin SOP Package for Quick Cold-Junction Thermocouple Compensation Thermal Response Portable Medical Equipment Shutdown Function Puts Device into a Low- Thermally Sensitive Systems that Require a High- Power Standby Mode Accuracy Analog-Output Temperature Sensor ORDERING INFORMATION PART TEMP RANGE PIN-PACKAGE Exposed Pad TYPICAL OPERATING CIRCUIT DS600U -40C to +125C 8 SOP Exposed Pad DS600U+ -40C to +125C 8 SOP Exposed Pad DS600U/T&R -40C to +125C 8 SOP 2.7V to 5.5V Tape-and-Reel DS600 Exposed Pad PAD DS600U+/T&R -40C to +125C 8 SOP Tape-and-Reel GND V DD + Denotes lead-free package.
