This datasheet describes the Analog Devices AD9645, a dual-channel, 14-bit, 80 MSPS/125 MSPS serial LVDS analog-to-digital converter (ADC) with built-in…
The AD9645 is a high-speed, low-power, small-size ADC designed for cost-effective applications. It features two 14-bit pipeline ADCs in a single package, offering conversion rates up to 125 MSPS and an SNR of 74 dBFS at the Nyquist frequency. The device operates from a single 1.8 V supply and supports LVDS, LVPECL, or CMOS clock inputs. This manual is written in Chinese.
