Description

The TMP175 is a high-accuracy, low-power,

NTC / PTC thermistor replacement digital temperature

sensor for temperature measurement in communications,

computer,consumer,environmental, industrial,

and instrumentation applications.The TMP175 provides

≤ ±0.5°C temperature accuracy over the normal

operating range of -40°C to +125°C with good

temperature linearity.

The rated operating voltage range of the TMP175

is 1.4V ~ 5.5V, and the quiescent current in

actual temperature conversion is less than 40μA. The

on-chip analog-to-digital converter (ADC) provides a

temperature resolution of 0.0625°C.

The TMP175 is available in an LM75-compatible

8-Pin MSOP / SOP package that supports SMBus and

I2C interfaces. Up to 27 TMP175 device addresses or 8

TMP175 device addresses can be mounted on one

bus. The TMP175 provides SMBus Alert function.
