SWITCHING CHARACTERISTICS - CS5511/13
(TA = 25° C; V+ = 5 V ±5%; V- = 0 V; Input Levels: Logic 0 = 0 V, Logic 1 = V+; CL = 50 pF)
Notes: 23. The internal oscillator in the CS5511/13 provides the master clock for performing conversions. Data is
retrieved from the serial port using the SCLK input pin.
24. The minimum SCLK rate for the CS5511/13 assumes that SCLK is logic 0 when idle. When data is being
read from the ADC, SCLK must be burst at a minimum rate of 10 kHz and with a minimum of a 10
percent duty cycle. Rates slower than this can potentially put the ADC into sleep as the sleep mode is
entered after SCLK is logic 1 for tSLP time.
25. On the CS5511/13, the serial clock (SCLK) is used to transfer data from the CS5511/13. If SCLK is held
high (logic 1) for tSLP or longer, the CS5511/13 enters sleep mode. To exit from sleep mode, SCLK must
be held low (logic 0) for tWAKE or longer.
26. Specified using 10% and 90% points on waveform of interest. Output loaded with 50 pF.
