AD9268 is a 16-bit, 80 MSPS/105 MSPS/125 MSPS, 1.8 V dual analog-to-digital converter (ADC) with a signal-to-noise ratio (SNR) greater than 70 dBFS, a peak-to-peak dynamic range (SFDR) of 88 dBc, and a low power consumption of 750 mW (at 125 MSPS).
The AD9268 is a dual, 16‑bit ADC designed for communications, software‑defined radio and broadband data applications. It operates from a single 1.8 V analog supply with a separate 1.8 V digital output driver supply, supporting both CMOS and LVDS output modes. Key features include up to 125 MSPS sample rate, 78 dBFS SNR at 70 MHz, 650 MHz analog input bandwidth, on‑chip dither, programmable internal reference, and a standard SPI serial interface for configuration and built‑in self‑test.
