IC Introduction

The SD5820A is a highly accurate temperature measurement IC. It supports single wire data communication and outputs 9 to 12 bits temperature readings. The maximum error is ±0.8℃ from -10℃ to +85℃ and ±1.5℃ over the full military temperature range of -55℃ to +125.
Over-temperature alarm thresholds can be set through internal register. Operating at “parasitic power” mode, the SD5820A derives power directly from the data line without the use of an external power supply.
Each chip has a unique 64-bits ID code useful for multi-slave communication system.
