TLE4997E2数据手册传感器变送器的磁性传感器-线性罗盘（IC）规格书PDF

描述 Description

The linear Hall IC TLE4997has been designed specifically to meet the demands of highly accurate rotation and position detection, as well as for current measurement applications. The sensor provides a ratiometric analog output voltage, which is ideally suited to Analog-to-Digital (A/D) conversion with the supply voltage as a reference. The IC is produced in BiCMOS technology with high voltage capability and also provides reverse polarity protection. Digital signal processing using a 16-bit DSP architecture and digital temperature compensation guarantees excellent stability over a long period of time. The minimum overall resolution is 12 bits. Nevertheless, some internal stages work with resolutions up to 20 bits.
