Multi-channel remote diode temperature sensor

摘要

A multi-channel remote diode temperature sensor that receives current flow across a plurality of remote diodes on a plurality of channels at a single negative data pin, is small in size and has reduced noise coupling between channels at the common negative data pin. The noise coupling of the multi-channel remote diode temperature sensor is minimized by placing an output of a low impedance buffer in electrical communication with the negative data pin. The voltage produced by the low impedance buffer automatically stabilizes the common mode voltage at the negative data pin. The size is minimized by configuring all channels of the multi-channel remote diode temperature sensor to share the sole negative data pin, thereby reducing pin count.
