Output Data Format
The conversion results are output on a dual 6-bit-wide
data bus. Data is latched into the ADC output latch fol-
lowing a pipeline delay of one clock cycle (Figure 8).
Output data is clocked out of the respective ADC’s data-
output pins (D_0 through D_5) on the rising edge of the
clock output (DCLK), with a DCLK-to-data propagation
delay (tPD) of 7.1ns. The MAX1002 outputs are TTL com-
patible.
Transfer Function
Figure 9 shows the MAX1002’s nominal transfer function.
Output coding is offset binary with 1LSB = FSR / 63.
