Completely Isolated, Robust, 4-Channel, Multiplexed Data Acquisition System for Industrial Level Signals

Circuit is a completely isolated, robust, industrial, 4-channel data acquisition system that provides 16-bit, noise free code resolution and an automatic channel switching rate of up to 42 kSPS. The channel to channel crosstalk at 42 kSPS switching is less than 15 ppm FS (less than -90 dB) because of the unique selection of fast settling components in the multiplexed signal chain
