CS5540

DS503PP1

5

Notes: 6. See Section 2.1, “Analog Input”.

7. See Section 2.2, “Voltage Reference Input”.

8. Absolute voltages on VREF+ and VREF- must be less than or equal to the supply voltages.

9. The CS5540 includes a digital filter. The filter which achieves simultaneous rejection of 50/60 Hz

provides single conversion settling at a 6.7 SPS throughput.

10. All outputs unloaded. All inputs at CMOS levels.
