3 Description

The TMP112-Q1 and TMP112D-Q1 devices are

digital temperature sensors designed for NTC/PTC

thermistor replacement where high accuracy is

required. These devices offer an accuracy of ±0.4°C/

±0.5°C without requiring calibration or external

component signal conditioning. TMP112-Q1 and

TMP112D-Q1 are highly linear and do not require

complex calculations or lookup tables to derive the

temperature. The calibrating for improved accuracy

feature in TMP112-Q1 (see the Calibrating for

Improved Accuracy section) allows users to calibrate

for an accuracy as good as ±0.17°C. The on-chip 12-

bit ADC offers resolutions down to 0.0625°C.

TMP112-Q1 and TMP112D-Q1 come with 0.8mm ×

0.8mm X2SON (DPW) and 1.6mm × 1.6mm SOT563

(DRL) packages. These devices feature SMBus™,

two-wire and I2C interface compatibility, and allow up

to four devices on one bus along with SMBus alert

function. These devices are specified to operate over

1.4V to 3.6V supply voltage. The maximum quiescent

current is around 10μA over the full operating range.
