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.
The MAX6631/MAX6632 perform a temperature-to-digital
conversion once every 8s and require minimal average
supply current, 32μA (typ). The MAX6629/MAX6630
perform a conversion once every 0.5s and require only
200μA (typ) supply current. Any of these temperature
sensors can perform conversions more often—up to
approximately four conversions per second by reading the
conversion results more often.
