Description

The TMP275AIDR is one number of the TMP275 series.The TMP275 is a 0.5 accurate, two-wire, serial output temperature sensor available in the MSOP-8 package. The TMP275 is capable of reading temperatures with a resolution of 0.0625.The TMP275 is SMBus-compatible and allows up to eight devices on one bus. It is ideal for extended temperature measurement in a variety of communication, computer,consumer, environmental,industrial, and instrumentation applications.

Features of the TMP275AIDR are:(1)8 addresses; (2)digital output: two-wire serial interface; (3)resolution: 9- to 12-bits, user-selectable; (4)accuracy:±0.5 (max) from +10 to +85,±0.75 (max) from +0 to +100; (5)low quiescent current:50A, 0.1A standby; (6)wide supply range: 2.7V to 5.5V; (7)small MSOP-8 package.The TMP275 features three address pins allowing up to eight devices to be connected per bus. Pin logic levels are described in Table 11. The address pins of the TMP275 are read after reset, at start of communication, or in response to a Two-Wire address acquire request. Following reading the state of the pins the address is latched to minimize power dissipation associated with detection.

The absolute maximum ratings of the TMP275AIDR can be summarized as:(1)power supply:7.0V; (2)input voltage:0.5V to 7.0V; (3)input current:10mA; (4)operating temperature range:55 to +127; (5)storage temperature range:60to +130; (6)junction temperature: +150.Stresses above these ratings may cause permanent damage.Exposure to absolute maximum conditions for extended periods may degrade device reliability. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those specified is not supported.The TMP275 operates only as a slave device on the Two-Wire bus and SMBus. Connections to the bus are made via the open-drain I/O lines SDA and SCL. The SDA and SCL pins feature integrated spike suppression filters and Schmitt triggers to minimize the effects of input spikes and bus noise. The TMP275 supports the transmission protocol for fast (1kHz to 400kHz) and high-speed (1kHz to 3.4MHz) modes. All data bytes are transmitted MSB first.
