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.
