SNIS214A – JUNE 2021 – REVISED SEPTEMBER 2021

TMP114 Ultra-Thin, 1.2-V to 1.8-V Supply, High Accuracy Digital Temperature Sensor

with I²C Interface

1 Features

3 Description

•

High accuracy

– TMP114:

The TMP114 is a high accuracy, I²C-compatible

digital temperature sensor in an ultra-thin (0.15 mm)

4-pin package. The small size and low height of

the TMP114 package optimizes volume constrained

systems and enables novel placement of the sensor

under other surface mount components for the fastest

and most accurate temperature measurement.

•

±0.3 °C maximum from –10 °C to 85 °C

±0.5 °C maximum from –40 °C to 125 °C

– TMP114N package option:

•

±1 °C maximum from –40 °C to 125 °C

•

Operating temperature range: –40 °C to +125 °C

16-bit resolution: 0.0078 °C (LSB)

Low power consumption:

– 0.7-µA average supply current

– 0.16-µA shutdown current

Supply range: 1.08 V to 1.98 V

1.2-V compatible logic inputs independent of

supply voltage

The TMP114 has an accuracy of ±0.3 °C and offers

an on-chip 16-bit analog-to-digital converter (ADC)

that provides a temperature resolution of 0.0078 °C.

The TMP114 is 100% tested on a production setup

that is NIST traceable.

•

To maximize battery life, the TMP114 is designed to

operate from a supply voltage range of 1.08 V to 1.98

V, with a low average supply current of less than 0.7

μA.

•

I²C and SMBus compatible interface

50-ns spike filter to coexist on I3C mixed bus

Optional Cyclic Redundancy Check (CRC)

300-ms response time
