Analog Devices TMP05ART-500RL7

Serial Switch/Digital Sensor, 12 Bit(s), 2Cel, Hybrid, Rectangular, 5 Pin, Surface Mount

The TMP05/TMP06 is a complete temperature monitoring system in 5-Lead SOT-23 and 5-Lead SC-70 packages. The TMP05/TMP06 are monolithic temperature sensors that generate a modulated serial digital output (PWM) that varies in direct proportion to the temperature of the devices. The single digital output of the TMP05/TMP06 is CMOS/TTL compatible, and is easily interfaced to the serial inputs of most popular microprocessors. The TMP05 has a push-pull output while the TMP06 has an open-drain output. The TMP05/TMP06 is rated for operation over the -40°C to +150°C temperature range. There are three mode s of operation. These are Continuously Converting, Daisy Chain and One Shot Mode. A tri-state FUNC input determines which mode the TMP05/TMP06 operates in. The CONV / IN input pin is used to determine the rate with which the TMP05/TMP06 measures temperature in Continuously Converting and in One Shot mode. In Daisy Chain Mode the CONV / IN pin operates as the input to the daisy chain.

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 (T H) of the PWM remains static over all temperatures, while the low period (T L) varies. The B Grade version offers a high temperature accuracy of +-1oC from 0oC to 70oC with excellent transducer linearity. The digital output of the TMP05/ TMP06 is CMOS/TTL compatible and is easily interfaced to the serial inputs of most popular microprocessors. The flexible open-drain output of the TMP06 is capable of sinking 5 mA. The TMP05/TMP06 are specified for operation at supply voltages from 3 V to 5.5 V. Operating at 3.3 V, the supply current is typically 370 uA. The TMP05/TMP06 are rated for operation over the -40oC to +150oC temperature range. It is not recommended to operate these devices at temperatures above 125oC for more than a total of 5% (5,000 hours) of the lifetime of the devices. They are packaged in low cost, low area SC-70 and SOT-23 packages.
