Overview
The AD734AN, produced by Analog Devices Inc., is a high-precision, 10 MHz four-quadrant analog multiplier. It is designed to be pin compatible with the industry-standard AD534 and is renowned for its high accuracy and speed. The AD734AN operates accurately on center frequencies up to 10 MHz, making it one of the fastest four-quadrant multipliers available in monolithic form. It features a novel translinear core and is laser trimmed to achieve a typical total error of less than 2% at 10 MHz. This component is highly versatile, capable of performing various analog signal processing functions beyond multiplication, including division, squaring, square root computation, and ratio-metric measurement.
