AD9268 is a 16-bit, 80 MSPS/105 MSPS/125 MSPS, 1.8 V dual analog-to-digital converter with low power, high performance, and high integration.
The AD9268 is a dual 16‑bit analog‑to‑digital converter designed for communications and high‑speed data applications. It operates from a single 1.8 V analog supply and a separate 1.8 V digital output driver supply, offering CMOS or LVDS output modes, on‑chip dither, and programmable SPI control.
Typical applications include broadband data links, software‑defined radios, smart antenna systems, and ultrasound equipment. The device is offered in a 64‑lead LFCSP package and is rated for an industrial temperature range of –40 °C to +85 °C.

The AD9268 uses a 1.8 V analog supply (AVDD) and a separate 1.8 V digital output driver supply (DRVDD).
The device defaults to CMOS output on power‑up; LVDS mode is selected by programming the SPI configuration registers after power‑up.
The AD9268 provides a differential analog input bandwidth of 650 MHz.
The part includes standby power of 45 mW and a power‑down mode with typical consumption of 0.5 mW.
