Operation
The MAX1150 has 255 preamplifier/comparator pairs;
each is supplied with the voltage from VRT to VRB,
divided equally by the resistive ladder as shown in the
Functional Diagram. This voltage is applied to the posi-
tive input of each preamplifier/comparator pair. An ana-
log input voltage applied at VIN is connected to the
negative inputs of each preamplifier/comparator pair.
The comparators are then clocked through each one’s
individual clock buffer. When the CLK pin is in the low
state, the master or input stage of the comparators com-
pares the analog input voltage to the respective refer-
ence voltage. When CLK changes from low to high, the
comparators are latched to the state prior to the clock
transition and output logic codes in sequence from the
top comparators, closest to VRT (0V), down to the point
where the magnitude of the input signal changes sign
(thermometer code). The output of each comparator is
then registered into four 64-to-6 bit decoders when CLK
is changed from high to low. At the output of the
decoders is a set of four 7-bit latches that are enabled
(track) when the clock changes from high to low. From
here, the output of the latches is coded into six LSBs
from four columns, and four columns are coded into two
MSBs. Finally, eight ECL output latches and buffers are
used to drive the external loads. The conversion takes
one clock cycle from the input to the data outputs.
