AD9637 is an 8-channel, 12-bit, 40/80 MSPS, serial LVDS, 1.8 V analog-to-digital converter from AD.
The AD9637 is an octal, 12‑bit analog‑to‑digital converter offering up to 80 MSPS conversion rate. It operates from a single 1.8 V supply and provides LVDS, CMOS, or LVPECL serial outputs, making it suitable for compact, low‑power applications.
The device includes programmable features such as digital test pattern generation, individual channel power‑down, and flexible clock and data alignment. It is supplied in a RoHS‑compliant 64‑lead LFCSP package and is rated for an ambient temperature range of –40 °C to +85 °C.
