AD8333 Datasheet (Analog Devices) - Dual I/Q Demodulator and Phase Shifter

AD8333, Dual I/Q Demodulator and Phase Shifter

The AD83331 is a dual phase-shifter and I/Q demodulator that enables coherent summing and phase alignment of multiple analog data channels.

It is the first solid-state device suitable for beamformer circuits, such as those used in high performance medical ultrasound equipment featuring CW Doppler.
