TMP7数据手册ABCircuits中文资料规格书

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.
