LX3302
Description
The LX3302 is a highly integrated programmable data conversion IC designed for interfacing to and managing of inductive sensors. The device includes an integrated oscillator circuit for driving the primary coil of an inductive sensor, along with two independent analog conversion paths for conditioning, converting, and processing of two analog signals from the secondary coils of the sensor. Each path includes an EMI filter, demodulator, anti-alias filter, programmable amplifier, and a 13-bit sigma-delta analog-to-digital converter.
Each analog signal path includes digital calibration capability which allows the plete analog path (including the external sensors) to be calibrated during the system manufacturing process. The calibration information is written to internal EEPROM resulting in improved production yields, and in-line system upgrades.
The LX3302 integrates a 32-bit RISC processor which provides programmable digital filtering and signal processing functions. The MCU...
