ADS5521集成电路（IC）的模数转换器（ADC）规格书PDF中文资料

ADS5521属于集成电路（IC）的模数转换器（ADC）。由德州仪器制造生产的ADS5521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 ADS5542 is a high-performance, 14-bit, 80 MSPS analog-to-digital converter (ADC). To provide a complete

converter solution, it includes a high-bandwidth linear sample-and-hold stage (S&H) and internal reference.

Designed for applications demanding the highest speed and highest dynamic performance in little space, the

ADS5542 has excellent power consumption of 545 mW at 3.3-V single-supply voltage. This allows an even

higher system integration density. The provided internal reference simplifies system design requirements.

Parallel CMOS-compatible output ensures seamless interfacing with common logic.

The ADS5542 is available in a 64-pin TQFP PowerPAD package over the industrial temperature range -40°C to

85°C.
