TLC5540CPW集成电路（IC）的模数转换器（ADC）规格书PDF中文资料

TLC5540CPW属于集成电路（IC）的模数转换器（ADC）。由德州仪器制造生产的TLC5540CPW模数转换器（ADC）模数转换器（ADC、A/D 或 A 转 D）对模拟信号进行采样，例如由麦克风采集的声音或传感器的输出，然后将其转换为数字信号。一般来说，数字输出是二进制补码二进制数，与输入成比例。输入类型可能是差分、伪差分或单端输入。模数转换器可按照位数、采样率、输入数、接口、转换器数和架构（例如自适应增量、双斜率、折叠、流水线、SAR、三角积分、两步式）进行选择。

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.
