General Description
The MAX6627/MAX6628 precise digital temperature
sensors report the temperature of a remote sensor. The
remote sensor is a diode-connected transistor, typically
a low-cost, easily mounted 2N3904 NPN type that
replaces conventional thermistors or thermocouples.
The MAX6627/MAX6628 can also measure the die tem-
perature of other ICs, such as microprocessors (Ps) or
microcontrollers (Cs) that contain an on-chip, diode-
connected transistor.
Remote accuracy is ±1°C when the temperature of the
remote diode is between 0°C and +125°C and the tem-
perature of the MAX6627/MAX6628 is +30°C. The tem-
perature is converted to a 12-bit + sign word with
0.0625°C resolution. The architecture of the device is
capable of interpreting data as high as +145°C from
the remote sensor. The MAX6627/MAX6628 tempera-
ture should never exceed +125°C.
These sensors are 3-wire serial interface SPI compat-
ible, allowing the MAX6627/MAX6628 to be readily con-
nected to a variety of Cs. The MAX6627/MAX6628 are
read-only devices, simplifying their use in systems
where only temperature data is required.
Two conversion rates are available, one that continu-
ously converts data every 0.5s (MAX6627), and one
that converts data every 8s (MAX6628). The slower ver-
sion provides minimal power consumption under all
operating conditions (30A, typ). Either device can be
read at any time and provide the data from the last con-
version.
Both devices operate with supply voltages between
+3.0V and +5.5V, are specified between -55°C and
+125°C, and come in space-saving 8-pin SOT23 and
lead-free TDFN packages.
