... Rates slower than this can potentially put the ADC into sleep as the sleep mode is entered after SCLK is logic 1 for t 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 t or longer, the CS5511/13 enters sleep mode. To exit from sleep mode, SCLK must ...

... When configured with an external master clock of 32.768 kHz, the filter in the CS5510/12 provides better than simultaneous 50 and 60 Hz line rejection, and outputs conversion words at 53.5 Sps. The CS5511/13 include an on-chip oscil- lator which eliminates the need for an external clock source. The CS5510/11/12/13 ADCs are designed to oper- ...

Due to the part-to-part variances in the osc oscillator frequency, the OWR of the CS5511/13 can vary between 53 Sps and 159 Sps ...

... Reading Conversions - CS5511/13 After power-up, the CS5511/13 begins converting and updating the output register. When there is new data in the output register (at the end of a con- version cycle) the SDO line will fall to a logic-low level also at a logic-low state (SDO will al- ways be high-impedance when CS is high) ...

... CS5510/12, switch- ing of a multiplexer should occur 595 SCLK cycles after SDO falls. For maximum throughput with the CS5511/13, switching of a multiplexer should oc- cur on the rising edge of SDO during a conversion in which the data word is not read. The conversion ...

... In the 20-bit devices (CS5512 and CS5513), multiple conversions can be averaged to arrive at a more accurate offset val- ue. In the 16-bit devices (CS5510 and CS5511), averaging may not be meaningful, because the noise will be below the size of one LSB when using nominal voltages for VREF (2 ...

... Schmitt trigger to allow for slow rise and fall time signals. If held high, the device will enter sleep mode. In the CS5510/12, this input is also used as a master clock source which determines conversion speeds and throughput. In the CS5511/13, SCLK is only used to read the conversion data and put the part in sleep mode. ...
