Understanding A/D Error Specs A perfect A/D transfer characteristic (staircase wave-form) is shown in Figure 11A. The horizontal scale is analog input voltage and the particular points labeled are in steps of 1 LSB (19.53mV with 2.5V tied to the ...

A correction is made to 1 offset the comparison by / LSB (see Figure 11A). 2 Analog Differential Voltage Inputs and Common- Mode Rejection This A/D gains considerable applications flexibility from the analog differential voltage input. The ...

Such an adjusted reference voltage can accommodate a reduced span or dynamic voltage range of the analog input voltage. If the analog input voltage were to range from 0.5V to 3.5V, instead 5V, the span would be ...

IC voltage regulators may be used for references if the ambient temperature changes are not excessive. Zero Error The zero of the A/D does not require adjustment. If the minimum analog input voltage value, V lN(MlN) zero offset can ...

Finally, if time is short and capacitive loading is high, external bus drivers must be used. These can be three-state buffers (low power Schottky is recommended, such as the 74LS240 series) or special higher-drive-current products which are designed as bus ...

This converter has been designed to directly interface with 8080/85 or Z-80 Microprocessors. The three-state output capability of the A/D eliminates the need for a peripheral interface device, although address decoding is still required to generate the appropriate CS for ...
