6 / 8 page MC14549B, MC14559B http://onsemi.com 6 TYPICAL APPLICATIONS Externally Controlled 6−Bit ADC (Figure 2) Several features are shown in this application: • Shortening of the register to six bits by feeding the seventh output bit into the FF input. • Continuous conversion, if a continuous signal is applied to SC. • Externally controlled updating (the start pulse must be shorter than the conversion cycle). • The EOC output indicating that the parallel data are valid and that the serial output is complete. Continuously Cycling 8−Bit ADC (Figure 3) This ADC is running continuously because the EOC signal is fed back to the SC input, immediately initiating a new cycle on the next clock pulse. Continuously Cycling 12−Bit ADC (Figure 4) Because each successive approximation register (SAR) has a capability of handling only an eight−bit word, two must be cascaded to make an ADC with more than eight bits. When it is necessary to cascade two SAR’s, the second SAR must have a stable resettable state to remain in while awaiting a subsequent start signal. However, the first stage must not have a stable resettable state while recycling, because during switch−on or due to outside influences, the first stage has entered a reset state, the entire ADC will remain in a stable non−functional condition. This 12−bit ADC is continuously recycling. The serial as well as the parallel outputs are updated every thirteenth clock pulse. The EOC pulse indicates the completion of the 12−bit conversion cycle, the end of the serial output word, and the validity of the parallel data output. Figure 2.
