Maxim Integrated Products introduces the DS7505 ±0.5 degrees Celsius accurate, digital temperature sensor and thermostat with nonvolatile memory (EEPROM). The integration of nonvolatile EEPROM enables this device to power-up with a user-defined configuration and thermostat thresholds, whereas other similar devices store threshold and configuration data in volatile memory and, therefore, can only power-up in the factory-defined state. Software and pin compatible with the industry-standard LM75 and Maxim's DS75, the DS7505 is ideal for applications that require high-accuracy temperature sensing, such as base-station, telecom, networking, and medical systems.
The DS7505 is factory calibrated to provide ±0.5 degrees Celsius accuracy over its entire supply-voltage range and a wide, 0 degrees Celsius to +70 degrees Celsius temperature range. It is ±2.0 degrees Celsius (max) accurate over its full, -55 degrees Celsius to +125 degrees Celsius operating-temperature range. Thermometer resolution is reported as user-selectable 9-, 10-, 11-, or 12-bit digital readings that translate to temperature increments between 0.5 degrees Celsius (9 bit) and 0.0625 degrees Celsius (12 bit).
To further enhance flexibility, the DS7505's user-defined configuration options include active or standby state, conversion resolution, thermostat mode, output polarity, and fault tolerance. Additionally, the nonvolatile thermostat and configuration registers allow the device to power-up and operate as a stand-alone thermostat with no need to communicate with a microcontroller.
The DS7505 operates from a low, 1.7V to 3.7V supply voltage and can, therefore, be connected directly to low-voltage supply rails. Because the device is function, pin, and software compatible with the popular LM75/DS75, it is easy to migrate to low-voltage and/or higher-precision designs using the DS7505. Communication with the DS7505 is achieved through a standard 2-wire (I2C) serial interface.
The DS7505 is available in a lead-free, 8-pin SO package; an 8-pin microSOP (microMAX(R)) package with an exposed pad is available as demand warrants. Prices start at $1.40 (1000-up, FOB USA).
