EVALUATION KIT AVAILABLE
12-Bit + Sign Temperature Sensor with
SPI-Compatible Serial Interface
General Description
The MAX6662 is a 12-bit + sign temperature sensor
combined with a programmable overtemperature alarm
and a 3-wire (SPI-compatible) serial interface in a single
package. It converts its die temperature into digital values
using an internal analog-to-digital converter (ADC). The
temperature data is stored in a temperature register as a
13-bit word, which allows 0.0625°C resolution. The tem-
perature data is readable at any time through the serial
interface. The operating temperature range is -55°C to
+150°C.
The MAX6662 provides two programmable watchdog
interrupt outputs. ALERT is used for lower temperature
warning functions, while OT is used for higher tempera-
ture-critical functions, such as power-supply shutdown.
The MAX6662 features a shutdown mode that saves
power by disabling everything except the serial interface.
The temperature sensor is available in an 8-pin SO pack-
age.

Note 1: The MAX6662 is not recommended to operate above +125°C for an extended period of time.
Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these
or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect
device reliability.
