This document provides detailed information about the AD8333, including its features, applications, and more.
The AD8333 is a dual‑phase shifter and I/Q demodulator that enables coherent summing and phase alignment of multiple analog channels. It is intended for use in medical imaging beamformers, phased‑array radar, and communication receivers.
Key features include 16 selectable phase steps (22.5° per step), a dynamic range of 159 dB/Hz, and a supply voltage of +5 V. The device is supplied in a 32‑lead LFCSP package rated for –40 °C to +85 °C operation and provides current‑mode I and Q outputs suitable for transimpedance conversion.
