CMOS Technology
description
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.
