Analog-digital converter / CMOS - CS550x series
The CS5505/06/07/08 family of low-power CMOS analog-to-digital (A/D) converters are ideal for measuring low-frequency signals representing physical, chemical, and biological processes.The CS5507/08 family members have single-channel differential analog and reference inputs, and the CS5505/06 members have four pseudo-differential analog input channels. The CS5505/07 family provides a 16-bit output word. The CS5506/08 provides a 20-bit output word. The CS5505/06/07/08 family samples upon command up to 100 output updates per second.
The on-chip digital filter offers superior line rejection at 50 Hz and 60 Hz when the device is operated from a 32.768 kHz clock (output word rate = 20 Hz).
The CS5505/06/07/08 family includes on-chip, self-calibration circuitry, which can be initiated at any time or temperature to ensure minimum offset and full-scale errors.
The CS5505/06/07/08 familys serial port offers two general-purpose modes for the direct interface to shift registers or synchronous serial ports of industry-standard microcontrollers.
