ADS62P42IRGCR

双通道14位， 125/105/80/65 MSPS ADC，具有并行CMOS / DDR LVDS输出 Dual Channel 14-Bit, 125/105/80/65 MSPS ADC with Parallel CMOS/DDR LVDS outputs

DESCRIPON

ADS62P4X is a dual channel 14-bit A/D converter family with maximum sample rates up to 125 MSPS. It combines high performance and low power consumption in a compact 64 QFN package. Using an internal sample and hold and low jitter clock buffer, the ADC supports high SNR and high SFDR at high input frequencies. It has coarse and fine gain options that can be used to improve SFDR performance at lower full-scale input ranges.
