Overview
The AD534JD, 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. This component is known for its high precision, with a maximum multiplication error of ±1% guaranteed for the AD534J grade without any external trimming. The AD534JD features fully differential, high impedance operation on all inputs, including the Z input, which enhances its flexibility and ease of use. The scale factor is pretrimmed to a standard value of 10.00 V and can be adjusted to lower values using an external resistor.
