description
The TLC5540 is a high-speed, 8-bit analog-to-digital converter (ADC) that converts at sampling rates up to
40 megasamples per second (MSPS). Using a semiflash architecture and CMOS process, the TLC5540 is able
to convert at high speeds while still maintaining low power consumption and cost. The analog input bandwidth
of 75 MHz (typ) makes this device an excellent choice for undersampling applications. Internal resistors are
provided to generate 2-V full-scale reference voltages from a 5-V supply, thereby reducing external
components. The digital outputs can be placed in a high impedance mode. The TLC5540 requires only a single
5-V supply for operation.
Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of
Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.
