The AD633 is a functionally complete, four-quadrant, analog multiplier. It includes high impedance, differential X and Y inputs and a high impedance summing input (Z). The low impedance output voltage is a nominal 10 V full scale provided by a buried Zener. The AD633 provides excellent performance and value and is an ideal choice for high precision, low cost analog multiplier applications.
The AD633 is a low‑cost, four‑quadrant analog multiplier offering high‑impedance differential X and Y inputs, a high‑impedance summing Z input, and laser‑trimmed accuracy. It provides up to 2 % total error over full scale and operates from a single supply.
It is supplied in 8‑lead plastic DIP (N) and 8‑lead plastic SOIC (RN‑8) packages, supports supply voltages from +8 V to +18 V, and features a 1 MHz small‑signal bandwidth, 20 V/µs slew rate, and the ability to drive capacitive loads, making it suitable for modulation, demodulation, voltage‑controlled amplifiers and other analog signal‑processing applications.
