Description

The ADC3683-xEP uses a serial LVDS (SLVDS) interface to output the data which minimizes the number of digital interconnects. The device supports two-lane, one-lane and half-lane options. The device is available in a 40-pin QFN package (5 mm x 5 mm) and supports the extended temperature range from -55 to +105⁰C
