TMP422AIDCNT

TEXAS INSTRUMENTS  TMP422AIDCNT  温度传感器芯片, 数字式, ± 1°C, -40 °C, +125 °C, SOT-23, 8 引脚

The is a Remote Temperature Sensor Monitor with a built-in local temperature sensor. The remote temperature sensor diode-connected transistors are typically, 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 The device include wide remote temperature measurement range up to +150°C and diode fault detection.
