Product Summary

The DS7505S+ is a low-voltage (1.7V to 3.7V) digital ther-mometer and thermostat provides 9-, 10-, 11-, or 12-bitdigital temperature readings over a -55℃ to +125℃ range with ±0.5℃ accuracy over a -0℃ to +70℃ range.A 9-bit resolution mode is software compatible with theLM75. Communication with the DS7505 is achievedthrough a simple 2-wire serial interface. Three addresspins allow up to eight DS7505S+ devices to operate on thesame 2-wire bus, which greatly simplifies distributed temperature-sensing applications. The applications of the DS7505S+ are (1)Networking Equipment; (2)Cellular Base Stations; (3)Office Equipment; (4)Medical Equipment; (5)Any Thermally Sensitive System.
