AD9241 is a 14-bit, 1.25MSPS monolithic A/D converter with low power consumption, single power supply, high precision and small size
The AD9241 is a 14‑bit, 1.25 MSPS monolithic analog‑to‑digital converter offered by Analog Devices. It operates from a single +5 V supply and delivers low power dissipation (≈60 mW) while providing excellent DC and AC performance, including 0.36 LSB rms input‑referred noise and a spurious‑free dynamic range of 88 dB.
The datasheet details the functional block diagram, pin assignments, absolute maximum ratings, electrical specifications, and typical performance curves. It also describes the flexible analog input architecture, which supports both single‑ended and differential configurations with programmable reference voltages.
