The MPY634 is a wide bandwidth, high accuracy, four- quadrant analog multiplier manufactured by Texas Instruments. It has wide bandwidth, high accuracy, easy to use, low cost, etc. It can be used for a variety of precision analog signal processing, modulation and demodulation, voltage-controlled amplifiers, video signal processing, etc.
The MPY634 analog multiplier offers a 10 MHz typical bandwidth and 40.5 % maximum four‑quadrant accuracy. It features differential X, Y, and Z inputs that allow configuration as a multiplier, squarer, divider, or square‑rooter, with an internal wide‑bandwidth op‑amp and low‑cost design.
The device is supplied at +15 V (operable down to +8 V) and draws 4–6 mA quiescent current. It is available in 14‑pin PDIP (MPY634KP) and 16‑pin SOIC (MPY634KU) packages, and supports scale‑factor adjustment from 0.1 to 10 via external resistors.

The MPY634 has a typical bandwidth of 10 MHz.
It is rated for +15 V supply but can operate down to +8 V, with reduced input and output range.
The scale factor can be set from 0.1 to 10 using external feedback resistors.
It is offered in a 14‑pin PDIP (MPY634KP) and a 16‑pin SOIC (MPY634KU) package.
