FIGURE 4-1: TC520 initialization & startup conversion timing relatioNships FIGURE 4-2: lOad value modify cycle 4.4.6 OPTO-ISOLATED APPLICATIONS The 3 wire serial port of the TC520A can be opto- isolated for applications requiring isolated data acquisi- tion. The additional control lines (LOAD, DV, READ) are normally not needed in such applications, but can also be brought across the isolation barrier with the addition of a second isolator. LOAD LOAD VALUE updated and conversion started TC520A Conversion State CE is pulled high only during AZ (DV = Low) New LOAD VALUE can be loaded (if so desired) TC520A held in AZ phase as long as CE = HIGH CE AZ INT IZ DINT AZ INT INT DINT IZ AZ AZ DIN, DCLK DV LOAD VALUE shifted into DIN Load Value LOAD LOAD VALUE updated and conversion started TC520A Conversion State CE AZ INT IZ DINT AZ INT INT DINT IZ AZ DIN, DCLK DV LOAD VALUE shift into DIN |
