SWITCHING CHARACTERISTICS - CS5510/12
(T
A
= 25° C; V+ = 5 V ±5%; V- = 0 V; Input
Levels: Logic 0 = 0 V, Logic 1 = V+; C
L
= 50 pF)
Notes: 20.
Device parameters are specified with 32.768 kHz clock; however, clocks up to 130 kHz (CS5510) or
200 kHz (CS5512) can be used for increased throughput. Higher clock rates will result in degraded
linearity specifications, as shown in Figures 14 and 15.
Specified using 10% and 90% points on waveform of interest. Output loaded with 50 pF.
On the CS5510/12, the serial clock input (SCLK) provides the master clock to operate the converter as
well as the serial data clock used to read conversion data. If SCLK is held high (logic 1) for t
SLP
or longer,
the CS5510/12 enters sleep. To exit from sleep mode, SCLK must be held low (logic 0) for t
WAKE
or
longer.
