7 / 54 page Notes: 14. CLKIN must be supplied whenever the CS5501 or CS5503 is not in SLEEP mode. If no clock is present when not in SLEEP mode, the device can draw higher current than specified and possibly become uncalibrated. 15. The CS5501/CS5503 is production tested at 4.096 MHz. It is guaranteed by characterization to operate at 200 kHz. 16. Specified using 10% and 90% points on waveform of interest. 17. In order to synchronize several CS5501’s or CS5503’s together using the SLEEP pin, this specification must be met. SWITCHING CHARACTERISTICS (TA = Tmin to Tmax; CLKIN=4.096 MHz; VA+, VD+ = 5V±10%; VA-, VD- = -5V ± 10%; Input Levels: Logic 0 = 0V, Logic 1 = VD+; CL = 50 pF; unless otherwise specified.)

All voltages with respect to ground. 13. The CS5501 and CS5503 can accept input voltages up to the analog supplies (VA+ and VA-). They will accurately convert and filter signals with noise excursions up to 100mV beyond |VREF|. After filtering, the devices will output all 1’s for any input above VREF and all 0’s for any input below AGND in unipolar mode and -VREF in bipolar mode. CS5501/CS5503 DS31F2 7 |
