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 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 TLC3544 and TLC3548 are designed to operate with low power
consumption. The power saving feature is further enhanced with software power-down/ autopower-down
modes 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 TLC3544 and TLC3548
have a 4-V internal reference. The converters are specified with unipolar input range of 0-V to 5-V when a 5-V
external reference is used.
