APPLICATIONS
Serial Data Output During a Conversion
Using Internal Clock for Conversion and Data Transfer.
Figure 17 shows data from the previous conversion being
clocked out during the conversion with the LTC1417
internal clock providing both the conversion clock and the
SCLK. The internal clock has been optimized for the fastest

best overall speed performance. To select the internal
conversion clock, tie EXTCLKIN (Pin 6) high. The internal
clock appears on CLKOUT (Pin 8) which can be tied to
SCLK (Pin 7) to supply the SCLK.
