ADL5391-EVALZ: 差分放大器

The ADL5391 draws on three decades of experience in advanced analog multiplier products. It provides the same general mathematical function that has been field proven to provide an exceptional degree of versatility in function synthesis:

VW = α × (VX x VY)/1 V + VZ

The most significant advance in the ADL5391 is the use of a new multiplier core architecture, which differs markedly from the conventional form that has been in use since 1970. The conventional structure that employs a current mode, translinear core, is fundamentally asymmetric with respect to the X and Y inputs, leading to relative amplitude and timing misalignments that are problematic at high frequencies. The new multiplier core eliminates these misalignments by offering symmetric signal paths for both X and Y inputs. The Z input allows a signal to be added directly to the output. This can be used to cancel a carrier or to apply a static offset voltage.

The ADL5391 is fabricated on Analog Devices' proprietary, high performance, 65 GHz, SOI complementary SiGe bipolar IC process. It is available in a 16-lead, Pb-free, LFCSP and operates over a -40°C to +85°C temperature range. Evaluation boards are available.
