MAX6629–MAX6632 12-Bit + Sign Digital Temperature Sensors with Serial Interface General Description The MAX6629–MAX6632 are local digital temperature sensors with an SPI-compatible serial interface. The temperature is converted to a 12-bit + sign word with a resolution of 0.0625°C/LSB. An extended temperature range provides useful readings up to +150°C. These sensors are 3-wire serial interface SPI compatible, allowing the MAX6629–MAX6632 to be readily connected to a variety of microcontrollers (μCs). The MAX6629– MAX6632 are read-only devices, simplifying their use in systems where only temperature data is required. All four digital temperature sensors require very little supply current, making them ideal for portable systems.
