AD734 is a 10MHz, 4-quadrant multiplier/divider from Analog Devices. It has high accuracy, high speed, low distortion, low noise, etc. It is suitable for applications such as multiplication, division, squaring, square root, modulation, demodulation, wideband gain control, RMS-DC conversion, voltage-controlled amplifiers, oscillators and filters.
The AD734 is a 10 MHz, 4‑quadrant analog multiplier/divider with a low typical error of 0.1 % and high speed performance. It offers a full‑power bandwidth of 10 MHz, a 450 V/µs slew rate, and low distortion (‑80 dBc) across the operating range. The device includes a direct‑division mode, external denominator control, and a differential input stage with low offset and bias currents.
The datasheet includes detailed electrical specifications, absolute maximum ratings, ordering information for various temperature‑grade packages, and functional block diagrams. It also describes connection diagrams, denominator‑control circuitry, and guidelines for achieving high accuracy in demanding applications such as modulators, demodulators, and RMS‑to‑DC conversion.
