TLC5540IPW屬于集成電路（IC）的模數轉換器（ADC）。由美國德州儀器公司制造生產的TLC5540IPW模數轉換器（ADC）模數轉換器（ADC、A/D 或 A 轉 D）對模擬信號進行采樣，例如由麥克風采集的聲音或傳感器的輸出，然后將其轉換為數字信號。一般來說，數字輸出是二進制補碼二進制數，與輸入成比例。輸入類型可能是差分、偽差分或單端輸入。模數轉換器可按照位數、采樣率、輸入數、接口、轉換器數和架構（例如自適應增量、雙斜率、折疊、流水線、SAR、三角積分、兩步式）進行選擇。

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.
