EVAL-ADA4622-2ARZ User Guide UG-1818 One Technology Way P.O. Box 9106 Norwood, MA 02062-9106, U.S.A. Tel: 781.329.4700 Fax: 781.461.3113 www.analog.com Evaluating the ADA4622-2 Low Bias Current, Single-Supply, Rail-to-Rail Output, Precision Op Amp The EVAL-ADA4622-2ARZ uses a combination of surface- FEATURES mount technology (SMT) in Case Size 0603, with the exception Full featured evaluation board for dual low bias current of bypass capacitors and termination resistors. The EVAL- amplifiers in narrow-body SOIC ADA4622-2ARZ evaluation board also features a variety of Enables quick prototyping unpopulated resistor and capacitor pads that provide the user User defined circuit configuration with multiple choices and extensive flexibility for different Edge mounted SMA connector provisions application circuits. Easy connection to test equipment and other circuits Available provision for photodiode for quick evaluation The evaluation board also has a provision for photodiode Connections available for photodiode bias sensors, allowing easy configuration of a transimpedance Guard trace available to minimize leakage amplifier (TIA). The layout is optimized with provisions for guarding to ensure low leakage and low parasitic capacitance for GENERAL DESCRIPTION TIA applications. This user guide describes the EVAL-ADA4622-2ARZ evaluation Full specifications of the ADA4622-2 can be found in the board, which allows users to test the ADA4622-2 but can also ADA4622-2 data sheet, available from Analog Devices, which be used for other dual, low bias current amplifiers that come in must be consulted in conjunction with this user guide when an 8-lead standard small outline package (SOIC N). The design using the EVAL-ADA4622-2ARZ. of this evaluation board emphasizes simplicity and ease of use. Provisions are available on the board to interface easily to test equipment.
