转速侦测ic（可精确到1/1024圆周）
ams5040.
工作电压：3v-5v
工作温度：-40c to 125c
封装：ssop16
ams5040内置霍尔传感器，外部元件少，整体成本远远低于传统的光学侦测系统。可编程控制测量精度，最大可达10bit即可将圆周分为1/1024（0.35度）。可输出数字数据或者U-V-W信号。
- Contact-less high resolution encoding over a full turn of
360 degrees
- Flexible system due to user programmable incremental
output modes:
- 10, 9, 8 or 7 bit user programmable resolution
- Quadrature A/B and index output signal
- Single channel output and direction indication
- U-V-W commutation signals for brushless DC motors
- Absolute angular position mode :
- 10-bit resolution providing 1024 absolute positions
per 360 degrees (step size ~ 0.35 degrees)
