Description

The TPTMP75 is a digital temperature sensor ideal for

replacement of negative temperature coefficient (NTC)

and positive temperature coefficient (PTC) thermistor.

The accuracy of the device is typical ± 1°C without

requirements of calibration or external signal conditioning.

The device includes an on-chip 12-bit analog-to-digital

converter (ADC), which offers resolutions down to

0.0625°C.

The device has SMBus, two-wire, and I2C interface

compatibility. It also has SMBUS Alert function.

The device is specified for operation over a temperature

range from −40°C to 125 °C.

The TPTMP75 is ideal for extended temperature

measurement in a variety of communication, computer,

consumer, environmental, industrial, and instrumentation

applications.
