APPLICATIONS
PACKAGE
LTC1418
allows the user to synchronize the A/D conversion to an
external clock either to have precise control of the internal
bit test timing or to provide a precise conversion time. As in
Figure 24, this mode works when the SCLK frequency is
very low (less than 30kHz). However, the external conver-
sion clock must be between 30kHz and 4.5MHz to maintain

accuracy. If more than 16 SCLKs are provided, more zeros
will be filled in after the data word indefinitely. To select the
external conversion clock tie EXT/INT high. The external
SCLK is applied to SCLK. RD can be used to gate the external
SCLK such that data will clock only after RD goes low.
