Description
The LX3301A 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 sine and cosine 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.
