1 Introduction

The TMP9R00-SP device is a radiation-hardened, high-accuracy, low-power 8-channel remote temperature sensor monitor with a built-in local temperature sensor. The remote temperature sensors are typically low-cost discrete NPN or PNP transistors, or substrate thermal transistors or diodes that are integral parts of microprocessors, analog-to-digital converters (ADC), digital-to-analog converters (DAC), microcontrollers, or field-programmable gate arrays (FPGA). Temperature is represented as a 13-bit digital code for both local and remote sensors, giving a resolution of 0.0625°C. The two-wire serial interface accepts the SMBus communication protocol with up to four different pin-programmable addresses.

Table 1-1 lists general device information and test conditions. See the TMP9R00-SP Product Page for more detailed technical specifications, user-guides, and application notes.⁽¹⁾
