Functional Description
The ADC10461, ADC10462 and ADC10464 digitize an ana-
log input signal to 10 bits accuracy by performing two
lower-resolution “flash” conversions. The first flash conver-
sion provides the six most significant bits (MSBs) of data,
and the second flash conversion provides the four least
significant bits LSBs).
Figure 3 is a simplified block diagram of the converter. Near
the center of the diagram is a string of resistors. At the
bottom of the string of resistors are 16 resistors, each of
which has a value 1/1024 the resistance of the whole resistor
string. These lower 16 resistors (the
LSB Ladder
) therefore
have a voltage drop of 16/1024, or 1/64 of the total reference
voltage (V
V
) across them. The remainder of the
resistor string is made up of eight groups of eight resistors
connected in series. These comprise the
MSB Ladder
.

CRD
) includes the
sampling time and is determined by the internal timer.
