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 compati-
ble, allowing the MAX6629–MAX6632 to be readily con-
nected 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-digi-
tal conversion once every 8s and require minimal aver-
age supply current, 32μA (typ). The MAX6629/
MAX6630 perform a conversion once every 0.5s and
Features
? Low Power Consumption
32 μ A typ (MAX6631/MAX6632)
200 μ A typ (MAX6629/MAX6630)
? 12-Bit + Sign Resolution with 0.0625°C/LSB
? Accuracy
±1°C (max) from 0°C to +70°C
? +150°C Extended Temperature Range
? SPI-Compatible Serial Interface

Ordering Information
require only 200μA (typ) supply current. Any of these
temperature sensors can perform conversions more
often—up to approximately four conversions per sec-
ond by reading the conversion results more often.
