LDC0851EVM TI近程,电感开发板EVAL BOARD FOR LDC0851-传感器

　　The Texas instruments LDC0851 evaluation module (EVM) helps designers evaluate the operation andperformance of the LDC0851 inductive Switch. The EVM contains one LDC0851 soldered onto the EVMPCB and options to operate with battery or USB power. A 50-k2 trim pot is also included to change theswitching distance threshold making it easy to evaluate for a wide variety of use cases.

　　EVM Interface

　　The LDC0851EVM can be powered with 5 V via the micro-USB connection (J3) on the top side of theEVM. Alternatively, a 3-V battery via the battery connection (BT1) on the backside of the EVM may beused to directly supply the LDC0851 with 3 V. Use Supply Switch (S2) to select the desired power sourceThe voltage on the ADJ pin of the LDC0851 at startup will determine the distance at which a l targetwill be detected, The voltaae can be easily controlled throuah the 50-k2 trim pot (R5). Note. the ADJ valueis only sampled once on startup or after EN has toggled low to high with switch S1.
