Description

The LX3302 is the second member of Microsemi’s new family

of smart sensor interface products. Designed to process

inductive sensors which are based upon linear variable

differential transformer (LVDT) principles, this new dee

integrates two complete analog channels, oscillator/exciter,

32-bit RISC processor, non-volatile configuration memory, and

four programmable I/O which support a variety of interface

options. In addition, the LX3302 provides internal 8kV (HBM)

ESD protection on the power, ground, and system interface

pins, eliminating the need for external protection components.
