description (continued)
In addition to being a high-speed ADC with versatile control capability, these devices have an on-chip analog
multiplexer (MUX) that can select any analog input or one of three self-test voltages. The sample-and-hold
function is automatically started after the fourth SCLK (normal sampling) or can be controlled by a special pin,
CSTART, to extend the sampling period (extended sampling). The normal sampling period can also be
programmed as short sampling (12 SCLKs) or long sampling (44 SCLKs) to accommodate the faster SCLK
operation popular among high-performance signal processors. The TLC3574/78 and TLC2574/78 are
designed to operate with low-power consumption. The power saving feature is further enhanced with
autopower-down mode and programmable conversion speeds. The conversion clock (internal OSC) is built in.
The converter can also use an external SCLK as the conversion clock for maximum flexibility. The TLC3574/78
and TLC2574/78 are specified with bipolar input and a full scale range of
±10 V.

NOTE: 4-Bit counter counts the CLOCK, SCLK. The CLOCK is gated in by CS falling edge if CS initiates the conversion operation cycle, or gated
in by the rising edge of FS if FS initiates the operation cycle. SCLK is disabled for serial interface when CS is high.
