Description
The TMP112 family of devices are digital temperature 
sensors designed for high-accuracy, low-power, 
NTC/PTC thermistor replacements where high 
accuracy is required. The TMP112A, TMP112B,

TMP112Dx offer 0.5°C accuracy and are optimized to 
provide the best PSR performance for 3.3V, 1.8V and 
≥1.5V operation respectively, while TMP112N offers 
1°C accuracy. These temperature sensors are highly 
linear and do not require complex calculations or 
lookup tables to derive the temperature. The on-chip 
12-bit ADC offers resolutions down to 0.0625°C.
The 1.6mm × 1.6mm SOT563 package is 68% 
smaller footprint than an SOT23 package while 
TMP112Dx utilizes ultra-small (0.64mm2) 5-pin 
package. The TMP112 family features SMBus,

two-wire and I2C interface compatibility, and allows up to 
four devices on one bus. The device also features 
an SMBus alert function or variant. The device is 
specified to operate over supply voltages from 1.4V 
to 3.6V with the typical quiescent current 3.2µA over 
the full operating range.
The TMP112 family is designed for extended 
temperature measurement in communication, 
computer, consumer, environmental, industrial, and 
instrumentation applications. The device is specified 
for operation over a temperature range of –40°C to 
125°C.
The TMP112 family production units are 100% 
tested against sensors that are NIST-traceable and 
are verified with equipment that are NIST-traceable 
through ISO/IEC 17025 accredited calibrations
