The AD8333 is a dual-phase shifter and I/Q demodulator with a frequency range of dc to 50 MHz. It features 16 phase select, phase accuracy of ±0.1°, and amplitude balance of ±0.05 dB. Applications include medical imaging, phased array systems, and communication receivers.
The AD8333 from Analog Devices is a dual‑phase shifter and I/Q demodulator designed for coherent summing and phase alignment in analog beamforming applications such as medical ultrasound, phased‑array radars, and communication receivers. It operates from DC to 50 MHz, provides 16 discrete phase rotations in 22.5° increments, and delivers a dynamic range of 159 dB/Hz per channel.
The device is supplied in a 32‑lead LFCSP package for an industrial temperature range of –40 °C to +85 °C. It includes logic interfaces for phase selection, enable, and reset, and requires a +5 V supply with a typical power consumption of 190 mW per channel.
