说明
the tlc548 and tlc549 are cmos analog-to-digital converter (adc) integrated circuits built around an 8-bit switched-capacitor successive-approximation adc. these devices are designed for serial interface with a microprocessor or peripheral through a 3-state data output and an analog input. the tlc548 and tlc549 use only the input/output clock (i/o clock) input along with the chip select (cs\) input for data control. the maximum i/o clock input frequency of the tlc548 is 2.048 mhz, and the i/o clock input frequency of the tlc549 is specified up to 1.1 mhz.
operation of the tlc548 and the tlc549 is very similar to that of the more complex tlc540 and tlc541 devices; however, the tlc548 and tlc549 provide an on-chip system clock that operates typically at 4 mhz and requires no external components.
