100 MHz TO 4000 MHz RF/IF Digitally Controlled VGA
Both the gain block and DSA are internally matched to 50 Ω at their inputs and outputs and are separately biased. The separate bias allows all or part of the ADL5240 to be used, which facilitates easy reuse throughout a design. The pinout of the ADL5240 also enables either the gain block or DSA to be first, giving the VGA maximum flexibility in a signal chain.
The ADL5240 consumes just 93 mA and operates from a single supply ranging from 4.75 V to 5.25 V. The VGA is packaged in a thermally efficient, 5 mm × 5 mm, 32-lead LFCSP and is fully specified for operation from −40°C to +85°C. A fully populated evaluation board is available.

This product has been released to the market. The data sheet contains all final specifications and operating conditions. For new designs, ADI recommends utilization of these products.
ADL5240-EVALZ is a fully populated, 4-layer, Rogers 3003-based evaluation board. For normal operation, it requires a 5 V/200 mA power supply. The evaluation board can be programmed through the USB port of a PC running Windows XP or Vista with Microsoft .NET Framework 3.5 installed. The required control software can be downloaded from www.analog.com. The DSA and the amplifier can be individually biased to the clip leads labeled VCC, VDD and GND as well as connected to the VDD plane using R2 and R1. The evaluation board can be configured with AMP-driving-DSA or DSA-driving-AMP using the available resistor and capacitor pads.
ADI has always placed the highest emphasis on delivering products that meet the maximum levels of quality and reliability. We achieve this by incorporating quality and reliability checks in every scope of product and process design, and in the manufacturing process as well. "Zero defects" for shipped products is always our goal.
