Overview
The AD534KD, produced by Analog Devices Inc., is a monolithic laser trimmed four-quadrant multiplier divider. It offers accuracy specifications previously found only in expensive hybrid or modular products. The AD534KD is part of the AD534 series, which includes various grades such as AD534J, AD534K, and AD534L, each with different maximum error specifications. The AD534KD, specifically, has a maximum multiplication error of ±0.5% and is specified for operation over the 0°C to +70°C temperature range.
