TC625CVZB 数据手册 ( 数据表 ) - TelCom Semiconductor, Inc

GENERAL DESCRIPTION
   The TC625 is a monolithic temperature sensor that generates a pulse train, the high and low times of which vary in direct proportion to the temperature of the device. This technique allows temperature to be accurately measured by the host microcontroller without an A/D converter, and with only a single I/O port pin. The overall accuracy is ±1.5°C typical over the rated measurement range of – 25°C to +100°C.
