为± 1A ° C远端温度和± 2.5A ℃，局部温度传感器SOT23-8 ±1°C REMOTE TEMPERATURE AND ±2.5°C LOCAL TEMPERATURE SENSOR IN SOT23-8

DESCRIPON

The TMP422 is a remote temperature sensor monitor with a built-in local temperature sensor. The remote temperature sensor diode-connected transistors are typically low-cost, NPN- or PNP-type transistors or diodes that are an integral part of microcontrollers, microprocessors, or FPGAs.

Remote accuracy is ±1°C for multiple IC manufacturers, with no calibration needed. The two-wire serial interface accepts SMBus write byte, read byte, send byte, and receive byte commands to configure the device.
