The document provides information about the collaboration between BDTI C and ADI companies.
The AD539 provides two identical signal channels with a common X‑input for linear gain control. It offers a 60 MHz (3 dB) signal‑channel bandwidth, a 5 MHz linear‑control‑channel bandwidth, and low distortion (≤0.01 %). The device is available in J, K, and S grades, in plastic or ceramic DIP packages and a MIL‑STD‑883 version.
Typical applications include high‑bandwidth AGC/VCA systems, voltage‑controlled filters, video‑signal processing, and high‑speed analog division. The datasheet includes detailed specifications, pin configuration, ordering guide, recommended PCB layout, and transfer‑function equations for multiplier and divider configurations.
