TLC2543CN

Product Summary

The TLC2543CN is 12-bit analog-todigital converter. The TLC2543CN has three control inputs [chip select (CS), the input-output clock (I/O CLOCK), and the address input (DATA INPUT)] and is designed for communication with the serial port of a host processor or peripheral through a serial 3-state output. The TLC2543CN allows high-speed data transfers from the host. In addition to the high-speed converter and versatile control capability, the TLC2543CN has an on-chip 14-channel multiplexer that can select any one of 11 inputs or any one of three internal self-test voltages. The sample-and-hold function is automatic. At the end of conversion, the end-of-conversion (EOC) output goes high to indicate that conversion is complete. The TLC2543CN is characterized for operation from TA = 0℃ to 70℃.
