Description

The CS5542 / CS5543 chip set is designed to be a complete current measurement data acquisition system. The CS5542 is a 22-Bit, 2-channel, 5th-order delta sigma modulator. The CS5543 is a monolithic CMOS, 8-channel digital FIR filter designed to be used with up to four CS5542’s forming an 8-channel system. The complete system is capable of cascading up to 1024 channels.
