DS75LXS+

The DS75LXS+ is a digital thermometer and thermostat with extended addressing in 8 pin NSOIC package. This low voltage digital thermometer and thermostat provides 9, 10, 11 or 12bit 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 DS75LX defaults to 9bit resolution for software compatibility with the LM75. Communication with the DS75LX is achieved through a simple 2-wire serial interface. Three tri-state address pins allow up to 27 DS75LX device to operate on the same 2-wire bus, which greatly simplifies distributed temperature sensing applications. The DS75LX thermostat has a dedicated open-drain output (O.S.) and programmable fault tolerance, which allow the user to define the number of consecutive error conditions that must occur before O.S. is activated. There are two thermostatic operating modes that control thermostat operation based on user-defined trip-points (TOS and THYST).
