CS5509

2

DS125F2

Notes: 1. Both source resistance and shunt capacitance are critical in determining the CS5509's source

impedance requirements. Refer to the text section Analog Input Impedance Considerations.

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

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 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-)).

7. All outputs unloaded. All inputs CMOS levels.
