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)
- Synchronous serial interface (SSI) output for absolute
position data
- Pulse width modulated (PWM) output
- User programmable zero and index position
- Failure detection mode for magnet placement monitoring
- Rotational speeds up to 10,000 rpm (incremental output)
- Push button functionality detects movement of magnet in
Z-axis
- Two supply voltages: 3.3 V or 5 V
- Wide temperature range: -40°C to + 125°C
- SSOP 16 package: 5.3mm x 6.2mm

资料已发，只要将ic正面对准轴中心即可，不需要接触，

有demo板可以演示
