DALLAS, TEXAS 75265
PRINCIPLES OF OPERATION
For certain applications, such as strobing applications, it is necessary to start conversion at a specific point in time.
This device accommodates these applications. Although the on-chip sample-and-hold function begins sampling
upon the high-to-low transition of the fourth I/O CLOCK cycle, the hold function does not begin until the high-to-low
transition of the eighth I/O CLOCK cycle, which should occur at the moment when the analog signal must be
converted. The TLC548 and TLC549 continue sampling the analog input until the high-to-low transition of the eighth
I/O CLOCK pulse. The control circuitry or software then immediately lowers I/O CLOCK and starts the holding function
to hold the analog signal at the desired point in time and starts the conversion.
