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.

PRODUCTION DATA information is current as of publication date.

Products conform to specifications per the terms of Texas Instruments

standard warranty. Production processing does not necessarily include

testing of all parameters.
