TMP7 IC

Thermometer with Seven Segment and Serial Output

General Description

The TMP7 is thermometer IC with seven segment outputs for non multiplexed displays. An

inexpensive thermister is used as the temperature sensor. The IC supports 4 scales: degrees C,

degrees F, percentage, and raw A/D output. Serial output is also provided for RS-232, USB, or

Ethernet operation. The chip provides output polarity control. The TMP7 has internal pull

resistors on inputs to minimize additional parts. A .1 uF bypass capacitor is suggested across the

VDD and VSS pins. The part uses the standard 28 pin .3 inch width SOIC and DIP packages.
