TMP112A
The TMP112A is a digital temperature sensor with
high-accuracy, low-power, and NTC/PTC thermistor repla-
cements. It can be used for extended temperature measu-
rement in communication,
computer, consumer electro-
nics,environmental, industrial and instrumentation applica-
tions. The TMP112A provides ≤ ±0.5°C temperature ac-
curacy with good temperature linearity over the normal
operating range of -40°C to +125°C.The TMP112A can pro-
vide extended temperature measurement mode, extending
the
temperature measurement range from
-55°Cto
+150°C.
The rated working voltage range of the TMP112A
is 1.4V~5.5V, and the maximum
quiescent current in
the entire working rage is 10µA (temperature measurement
frequency 4Hz).The on-chip 12-bit ADC offers resolutions
down to 0.0625°C.
The TMP112A adopts SOT563 is compatible with
SMBus and I2C interface, and allows up to four devices
on one bus. The device also features an SMBus alert func-
tion.
