Notes: 22. No pin should go more positive than (VA+)+0.3V.
           23. VD+ must always be less than (VA+)+0.3 V,and can never exceed 6.0V.
           24. Applies to all pins including continuous overvoltage conditions at the analog input (AIN) pin.
           25. Transient currents of up to 100mA will not cause SCR latch-up. Maximum input current for a power
                 supply pin is ± 50 mA.

* WARNING: Operation at or beyond these limits may result in permanent damage to the device. Normal operation
                     is not guaranteed at these extremes.


Description

The CS5505/6/7/8 are a family of low power CMOS A/D converters which are ideal for measuring low-frequency signals representing physical, chemical, and biological processes.

The CS5507/8 have single-channel differential analog and reference inputs while the CS5505/6 have four pseudo-differential analog input channels. The CS5505/7 have a 16-bit output word. The CS5506/8 have a 20-bit output word.The CS5505/6/7/8 sample upon command up to 100 output updates per second.

The on-chip digital filter CS5505 offers superior line rejection at 50 and 60 Hz when the device is operated from a 32.768 kHz clock (output word rate = 20 Hz.).

The CS5505/6/7/8 include on-chip self-calibration circuitry which can be initiated at any time or temperature to ensure minimum offset and full-scale errors.

The CS5505/6/7/8 serial port offers two general-purpose modes for the direct interface to shift registers or synchronous serial ports of industry-standard microcontrollers.
