IC Introduction

SD5020 is a highly accurate temperature measurement IC. It supports single wire bus communication and outputs 12 bits temperature readings. The typical error is ±0.5for the -10~+85range, and ±0.8for the -55~+125range. Over-temperature alarm thresholds and hysteresis can be set through internal register.
Each chip has a unique 40 bits address useful for multi-slave communication system.
