说明

ADC3660 器件是一款低噪声、超低功耗、16 位、65MSPS 双通道高速模数转换器 (ADC)。该器件可实现低功耗,噪声频谱密度为 –159dBFS/Hz,还具有出色的线性度和动态范围。ADC3660 可实现出色的直流精度以及中频采样支持,因此是各种应用的出色选择。该 ADC 在 65MSPS 下的功耗仅为每通道 71mW,功耗随采样率减小而迅速降低。在旁路模式(最高 31MSPS)下,您可以在 1 或 2 个时钟周期后获取输出数据。

ADC3660 使用串行 CMOS (SCMOS) 接口输出数据,可更大限度减少数字互连的次数。该器件提供双通道、单通道和半通道选项。串行 CMOS 接口支持高达 250Mbps 的输出速率,相当于在复杂抽取后大约 15MSPS(双线)到大约 3.75MSPS(0.5 线)的输出速率。因此,ADC3660 可以使用内部抽取滤波器在“过采样和抽取”模式下运行,从而改进动态范围并省去外部抗混叠滤波器。

该器件采用 40 引脚 WQFN 封装(5mm × 5mm),支持 –40 至 +105⁰C 的工业级工作温度范围。
