DESCRIPTION
The DS75 digital thermometer and thermostat provides 9, 10, 11, or 12-bit digital temperature readings over a -55°C to +125°C range with ±2°C accuracy over a -25°C to +100°C range. At power-up, the DS75 defaults to 9-bit resolution for software compatibility with the LM75. Communication with the DS75 is achieved via a simple 2–wire serial interface. Three address pins allow up to eight DS75 devices to operate on the same 2–wire bus, which greatly simplifies distributed temperature sensing applications.
