important, the capacitor only has to charge to within 1 bit (called 1 LSB) of the
input voltage; for a 10 V converter with a 4 V input range, this is 8 V/1024, or
7.8 mv. This is an important concept that we will take a closer look at in Chapter
9. To simplify the concept, errors that fall within one bit of resolution have no
effect on conversion accuracy. The other side of that coin is that the accumulation
of errors (opamp offsets, gain errors, etc.) cannot exceed one bit of resolution or
they will affect the result.
Clocked Interfaces
Interfacing the MAX151 to a clocked bus, such as that implemented on the Intel
80960 family, is shown in Figure
