Notes: 21. No pin should go more positive than (VA+)+0.3V.
22. VD+ must always be less than (VA+)+0.3V, and can never exceed +6.0 V.
23. Applies to all pins including continuous overvoltage conditions at the analog input (AIN) pin.
24. Transient currents of up to 100mA will not cause SCR latch-up. Maximum input current for a power
supply pin is ± 50 mA.
25. Total power dissipation, including all input currents and output currents.
* WARNING: Operation at or beyond these limits may result in permanent damage to the device. Normal operation
is not guaranteed at these extremes.

DescriptionThe CS5509 is a single supply, 16-bit, serial-output CMOS A/D converter. The CS5509 uses charge-balanced (delta-sigma) techniques to provide a low cost, high resolution measurement at output word rates up to 200 samples per second.
The on-chip digital filter CS5509 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 CS5509 has on-chip self-calibration circuitry which can be initiated at any time or temperature to ensure minimum offset and full-scale errors.
Low power, high resolution and small package size make the CS5509 an ideal solution for loop-powered transmitters, panel meters, weigh scales and battery
