Maxim has introduced a highly accurate digital temperature sensor and thermostat with non-volatile EEPROM memory.
The integration of non-volatile EEPROM enables the DS7505 to power-up with a user-defined configuration and thermostat thresholds. Software and pin compatible with the industry-standard LM75 and Maxim’s DS75, the new device is suitable for applications that require high-accuracy temperature sensing, such as base-stations, telecom, networking and medical systems.
The DS7505 is factory calibrated to provide ±0,5°C accuracy over its entire supply-voltage range and a wide, 0°C to +70°C temperature range. It is ±2,0°C accurate over its full, -55°C to +125°C 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°C (9 bit) and 0,0625°C (12 bit).
To further enhance flexibility, the device’s user-defined configuration options include active or standby state, conversion resolution, thermostat mode, output polarity and fault tolerance. Additionally, the non-volatile thermostat and configuration registers allow the device to power-up and operate as a standalone thermostat with no need to communicate with a microcontroller.
The DS7505 operates from a 1,7 V to 3,7 V supply voltage and can, therefore, be connected directly to low-voltage supply rails. Communication is achieved through a standard 2-wire (I²C) serial interface.
