Overview
The AD532SD, produced by Analog Devices Inc., is a pretrimmed, single chip, monolithic multiplier/divider. It is the first of its kind, offering a maximum multiplying error of ±1.0% and a ±10 V output voltage without the need for external trimming resistors or an output op amp. The internal trimming of the AD532SD simplifies its use, making it an attractive alternative to modular multipliers. Its monolithic construction provides advantages in size, reliability, and economy, and it can be used as a direct replacement for other IC multipliers that require external trim networks.
