Melexis MLX90821 Relative Pressure Sensors
Melexis MLX90821 Relative Pressure Sensors are factory-calibrated relative pressure sensors that deliver a ratiometric analog output or a digital ** using the SENT protocol. MLX90821 features a MEMS sensor that enables reliable and accurate measurement of low pressures of a few tenths of millibars. These Melexis relative pressure sensors include an optimized architecture and high-density CMOS technology. These design features provide leading automotive electromagnetic compatibility (EMC) performance. The digital-**-processor architecture uses a 16-bit microcontroller to provide high initial accuracy of pressure and optional external NTC temperature.

TLV和TPS一般会有pin to pin的对应型号；
一般来讲，TPS精度、准确度和性能会好一些，所以价钱要贵一些；
对应TLV就是一样可以实现上述功能，但是精度和性能等级是稍微低一点的；
具体选择原则，这个要看你的需求了，需要高性能就采用TPS，如果更看重成本可以选择TLV；
TPS的意思就是Ti Performance Solution, TLV 就是就是高性价比（Low Value）。
