ADS6124 具有可选并行 CMOS 或 LVDS 输出的低功耗 12 位 105MSPS ADC

ADS6125/ADS6124/ADS6123/ADS6122 (ADS612X) is a family of 12-bit A/D converters with sampling frequencies up to 125 MSPS. It combines high performance and low power consumption in a compact 32 QFN package. Using an internal high bandwidth sample and hold and a low jitter clock buffer helps to achieve high SNR and high SFDR even at high input frequencies.

It features coarse and fine gain options that are used to improve SFDR performance at lower full-scale analog input ranges.

The digital data outputs are either parallel CMOS or DDR LVDS (Double Data Rate). Several features exist to ease data capture such as — controls for output clock position and output buffer drive strength, and LVDS current and internal termination programmability.
