Box 17847, Austin, Texas 78760 (512) 445 7222 FAX: (512) 445 7581 http://www.crystal.com CS5542 CS5543 22-Bit, Multi-Channel ∆Σ ADC Chip Set Features l Delta-Sigma Architecture: - 5th Order Modulator - 22-Bit Resolution l dc Accuracy (fBW = 250Hz): - Integral Linearity: ±0.001 % F.S. - Differential Linearity: ±0.5 LSBs - RMS Noise: 1.1 pARMS l Pin Selectable Input Range: - ±400 nA to ±2.5 µA Full Scale l 8-Channel Digital FIR Filter l Self-calibration of Offset and Gain l Low Power: 50 mW /ch for 8-ch system Description The CS5542 / CS5543 chip set is designed to be a com- plete current measurement data acquisition system. The CS5542 is a 22-Bit, 2-channel, 5th-order delta sig- ma 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 com- plete system is capable of cascading up to 1024 channels. The system supports 22-bit measurement resolution with output conversion rates up to 1 kHz per channel. JTAG boundary-scan capability is available to facilitate self-test at the system level. Potential applications for the CS5542/CS5543 system are environmental monitoring, process control systems, color sensing, light measurement, chemical analyzers and photo-diode transducer applications.
