8 位 40MSPS ADC 单通道，内部 S，低功耗
The 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.
