The TMP05/TMP06 have three modes of operation: continuously converting mode, daisy-chain mode, and one shot mode. A three-state FUNC input determines the mode in which the TMP05/TMP06 operate. The CONV/IN input pin is used to determine the rate with which the TMP05/TMP06 measure temperature in continuously converting mode and one shot mode. In daisy-chain mode, the CONV/IN pin operates as the input to the daisy chain.
GENERAL DESCRIPTION
The TMP05/TMP06 are monolithic temperature sensors that generate a modulated serial digital output (PWM), which varies in direct proportion to the temperature of the devices. The high period (TH) of the PWM remains static over all temperatures, while the l……
