Tel: 781.329.4700 Fax: 781.461.3113 www.analog.com Evaluation Board for Differential Amplifiers Offered in 8-Lead SOIC Packages FEATURES The 8-lead SOIC evaluation board is a bare board (that is, no Flexible board layout allows for various circuit components are soldered to the board) that enables users to configurations quickly prototype a variety of differential driver circuits, thereby Accommodates the ADA4940-1 and the AD813x family minimizing risk and reducing time to market. The board layout of differential amplifiers in 8-lead SOIC packages is very flexible and allows for many circuit configurations, includ- Enables quick breadboarding/prototyping ing traditional four-resistor circuits, circuits with two different Edge-mounted SMA connector provisions feedback loops, filters, and many others. Most resistors and Easy connection to test equipment and other circuits capacitors use 1206, 0402, 0508, and 0603 packages. RoHS compliant Figure 1 shows the component side of the bare evaluation board, and Figure 2 shows the circuit side of the evaluation board. GENERAL DESCRIPTION Because this universal evaluation board can be used with many The Analog Devices, Inc., 8-lead SOIC evaluation board for Analog Devices differential amplifiers in 8-lead SOIC packages, differential drivers is designed to help users evaluate differential the evaluation board label does not contain specific part numbers. drivers offered in 8-lead standard small outline (SOIC) packages. The board accommodates the ADA4940-1, as well as many The 8-lead SOIC differential driver evaluation board makes it members of the AD813x family of differential amplifiers (see the easy for designers to obtain quick performance results for their Related Links section). The data sheets for these devices should specific differential driver application circuits. be consulted in conjunction with this evaluation board user guide.
