TMP7中文资料Thermometer IC with Seven Segment and Serial Outputs数据手册ABCircuits规格书

描述 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.
