Sensors

Remote / multi-channel temperature sensors

Monitor up to 9 locations from a single, integrated temperature sensor

Remote diode temperature sensors measure the temperature of external PN junctions such as diodes or transistors. Often times FPGAs, ASICs, or processors will pin a thermal diode on chip allowing for a remote diode temperature sensor to measure FPGA temperature directly.
