说明
ADS62C17 is a dual channel 11-bit, 200 MSPS A/D converter that combines high dynamic performance and low power consumption in a compact 64 QFN package. This makes it well-suited for multi-carrier, wide band-width communications applications.

ADS62C17 uses TI-proprietary SNRBoost technology that can be used to overcome SNR limitation due to quantization noise for bandwidths less than Nyquist (Fs/2). It includes several useful and commonly used di*al functions such as ADC offset correction, gain (0 to 6 dB in steps of 0.5 dB) and gain tuning (in fine steps of 0.001 dB).

The gain option can be used to improve SFDR performance at lower full-scale input ranges. Using the gain tuning capability, each channel’s gain can be set independently to improve channel-to-channel gain matching.

ADS62C17是一个双通道11位，200 MSPS A / D转换，结合在一个紧凑的64 QFN封装的高动态性能和低功耗。这使得它*适合多载波，宽带宽通信应用。

ADS62C17采用TI专有的SNRBoost技术可用于克服信噪比由于量化噪声的带宽小于奈奎斯特（FS / 2）的限制。它包括几个有用的和常用的数码功能，如ADC的偏移校正，增益（0至6分贝步长为0.5分贝）和增益调整（精度0.001分贝）。

增益选项，可用于*在较低的满量程输入范围的SFDR性能。使用增益调整功能，每个通道的增益可以*设置，以*通道对通道增益匹配。
