1 of 4 REV: 040804 Note: Some revisions of this device may incorporate deviations from published specifications known as errata. Multiple revisions of any device may be simultaneously available through various sales channels. For information about device errata, click here: www.maxim-ic.com/errata. GENERAL DESCRIPTION The DS600 is a ±0.5°C accurate analog-output temperature sensor. This accuracy is valid over its entire operating voltage range of 2.7V to 5.5V and the wide temperature range of -20°C to +100°C. The DS600 can also act as a thermostat, with user- programmable trip points. A shutdown mode enables the DS600 to be placed in a low-power standby state. The DS600 is available in an 8-pin µSOP package.
