Description
The CS5508 is a family of low power CMOS A/D converters which are ideal for measuring low-frequency signals representing physical, chemical, and biological processes. The CS5508 have single-channel differential analog and reference inputs while the CS5505/6 have four pseudo-differential analog input channelsThe CS5508 have a 20-bit output word.The CS5508 sample upon command up to 100 Sps. The on-chip digital filter offers superior line rejection at 50 and 60 Hz when the device is operated from a 32.768 kHz clock (output word rate = 20 Sps). The CS5508 include on-chip self-calibration circuitry which can be initiated at any time or temperature to ensure minimum offset and full-scale errors. The CS5508 serial port offers two general-purpose modes for the direct interface to shift registers or synchronous serial ports of industry-standard microcontrollers.
