LTC2512-24 APPLICATIONS INFORMATION
Filtered Output Data, No Latency Data, Single Device
shared SDO bus at a time in order to avoid bus conflicts. As shown in Figure 34, the RDLA and RDLB inputs idle Figure 34 shows a single LTC2512-24 configured to read high and are individually brought low to read data from both filtered and no latency output data, while sharing each serial output when data is available. When RDLA SDOA with SDOB and SCKA with SCKB. Sharing signals is brought low, the MSB of the filtered output data from reduces the total number of required signals to read both SDOA is output on the shared SDO bus. When RDLB is the filtered and no latency data from the ADC. Since SDOA brought low, the MSB of the no latency data output from and SDOB are shared, the RDLA and RDLB inputs of the SDOB is output on the shared SDO bus. ADC must be used to allow only one output to drive the RDLA RDLB MASTER CLK MCLK DIGITAL HOST RDLA DRL RDLB IRQ LTC2512-24 SDOA DATA IN SEL0 SEL1 SDOB SCKA SCKB CLK CONVERT POWER-DOWN AND ACQUIRE CONVERT tMCLKL MCLK DRL tDRLLH BUSY tCONV tBUSYLH RDLA RDLB tSCKA tSCKB t t t QUIET SCKAH SCKBH SCKA/ SCKB 1 2 3 22 23 24 25 26 27 44 45 46 tHSDOA tSCKAL tSCKBL tENB tHSDOB t t ENA t DISA DSDOA tDSDOB SDOA/ Hi-Z Hi-Z Hi-Z SDOB DA23 DA22 DA21 DA1 DA0 CB7 DB13 DB12 DB11 CB1 CB0 251224 F34
