Texas Instruments TMP423

the tmp421 tmp422 and tmp423 are remote temperature sensor monitors with a built- local temperature sensor. the remote temperature sensor diode-connected transistors are typically low-cost npn- or pnp-type transistors or diodes that are an tegral part of microcontrollers microprocessors or fpgas. remote accuracy is 1c for multiple ic manufacturers with no calibration needed. the two-wire serial terface accepts smbus write byte read byte send byte and receive byte commands to configure the device. the tmp421 tmp422 and tmp423 clude series resistance cancellation porgrammable non-ideality factor wide remote temperature measurment range (up to +150c) and diode fault detection.
