AD534 is a four-quadrant precision IC multiplier produced by AD company. Its features are high precision, high input impedance and up to X100 gain. This product is widely used in high quality analog signal processing, differential ratio and percentage computation, algebraic and trigonometric function synthesis, wideband high crest rms to dc conversion and accurate voltage controlled oscillators and filters.
The AD534 is a monolithic, laser‑trimmed four‑quadrant multiplier/divider offering up to ±100× gain with a typical low‑noise performance of 90 pV rms (10 Hz‑10 kHz). It provides fully differential, high‑impedance inputs on X, Y and Z, allowing flexible signal processing such as multiplication, division, squaring and square‑rooting.
The device is available in several grades (J, K, L, S, T) and in TO‑100 (H‑10A) and TO‑116 (D‑14) packages, as well as an LCC (E‑20A) option. It operates from a supply voltage of +8 V to +18 V, with a rated performance of +15 V, and includes ESD protection circuitry.
