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 anew multiplier core architecture, which differs markedly fromthe conventional form that has been in use since 1970. Theconventional structure that employs a current mode, translinearcore is fundamentally asymmetric with respect to the X and Yinputs, leading to relative amplitude and timing misalignmentsthat are problematic at high frequencies. The new multiplier coreeliminates these misalignments by offering symmetric signalpaths for both X and Y inputs. The Z input allows a signal to beadded directly to the output. This can be used to cancel a carrieror to apply a static offset voltage.
The fully differential X, Y, and Z input interfaces are operationalover a ±2 V range, and they can be used in single-ended fashion.The user can apply a common mode at these inputs to varyfrom the internally set VPOS/2 down to ground. If these inputsare ac-coupled, their nominal voltage will be VPOS/2. These inputinterfaces each present a differential 500 Ω input impedance up toapproximately 700 MHz, decreasing to 50 Ω at 2 GHz. The gainscaling input, GADJ, can be used for fine adjustment of the gainscaling constant (α) about unity.
The differential output can swing ±2 V about the VPOS/2common-mode and can be taken in a single-ended fashion aswell. The output common mode is designed to interface directlyto the inputs of another ADL5391. Light dc loads can be groundreferenced; however, ac-coupling of the outputs is recommendedfor heavy loads.
The ENBL pin allows the ADL5391 to be disabled quickly to astandby mode. It operates off supply voltages from 4.5 V to 5.5 Vwhile consuming approximately 130 mA.
The ADL5391 is fabricated on Analog Devices, Inc. proprietary,high performance, 65 GHz, SOI complementary, SiGe bipolarIC process. It is available in a 16-lead, RoHS compliant, LFCSPand operates over a −40°C to +85°C temperature range.Evaluation boards are available.
