The MAX6629MAX6632 are local digital temperature sensors with an SPITM-compatible serial interface. The temperature is converted to a 12-bit + sign word with a resolution of 0.0625C/LSB. An extended temperature range provides useful readings up to +150C. These sensors are 3-wire serial interface SPI compatible, allowing the MAX6629MAX6632 to be readily connected to a variety of microcontrollers (Cs). The MAX6629MAX6632 are read-only devices, simplifying their use in systems where only temperature data is required.
