... The converted data (plus overrange and polarity bits) are held in an 18-bit shift register until read by the processor or until the next conversion is completed. Data may be clocked out of the TC520A at any time, and at any rate, the user prefers. A Data Valid (DV) out- put is driven active at the start of each conversion cycle, indicating the 18-bit shift register update has just been completed ...

... TC5XX A/D converter. A high-to-low state change on this pin causes the TC520A to terminate the de-integrate phase of conversion. Output, active high. The A and B outputs of the TC520A connect directly to the A and B inputs of the TC5XX A/D converter connected to the TC520A. The binary code determines the conversion phase of the TC5XX A/D converter: ( places the TC5XX A/D converter into the Auto Zero phase ...

... Low Output, active low brought low any time the TC520A is in the AZ phase of con- version. This occurs when, either the TC520A initiates a normal AZ phase by setting A, B, equal to 01, or when CE is pulled high, which overrides the normal A, B sequencing and forces an AZ state returned high when the TC520A exits AZ. ...

... TC5XX A/D Converter Control Signals The TC520A control outputs (A, B) and control input (CMPTR) connect directly to the corresponding pins of the TC5XX A/D converter. A conversion is consum- mated when A, B have been sequenced through the required 4 phases of conversion: Auto Zero (AZ), Inte- ...

... EQUATION 4-1: LOAD VALUE = In this example, LOAD VALUE = 128 fore, a LOAD VALUE of 10H is loaded into the TC520A. If the desired T the LOAD VALUE would be 9EH, and so on. The TC520A LOAD VALUE must be initialized on power-up, and can be re-initialized as often as desired thereafter. ...

... CLK DV 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 ...
