2. Specifications guaranteed by design, characterization and/or test.
3. Applies after calibration at the temperature of interest.
4. Total drift over the specified temperature range since calibration at power-up at 25 °C.
5. The input is differential. Therefore, GND ≤ Signal + Common Mode Voltage ≤ VA+.
6. The CS5509 can accept input voltages up to the VA+ analog supply. In unipolar mode the CS5509 will

0's if the input becomes more negative than 0 Volts. In bipolar mode the CS5509 will output all 1's if the
dc input magnitude ((AIN+) - (AIN-)) exceeds ((VREF+) - (VREF-)) and will output all 0's if the input
becomes more negative in magnitude than -((VREF+) - (VREF-)).
