OPAMP1EVB Op Amp Evaluation Board Manual SOT23, SC70, and SOIC8 Package http://onsemi.com Description This document describes the SOT23, SC70, and SOIC8 package Op Amp evaluation board. It should be used in conjunction with the appropriate data sheet which contains full technical details on the device specification and operation. This evaluation board is offered as a convenience for the customers interested in performing their own engineering characterization and performance assessment. The evaluation board provides a 50 W controlled impedance environment. The evaluation board is designed to facilitate a quick evaluation of the device. The default populated evaluation board will have a gain of two. • Information on OP1SC70EVB (SC70 package) • • Evaluation Board Information on OP1SOIC8EVB (SOIC8 package) Evaluation Board Bill of Materials Board Lay−up The SOT23, SC70, and SOIC8 evaluation boards are implemented in two layers (Figure 1, Evaluation Board Lay−up). The first layer is the 1.0 oz copper ground plane, where a portion of the ground plane is cut out to mount the device. The FR4 dielectric material is placed between the first and second layer. The second layer contains the rest of the components and primary signal traces.

Evaluation Board Lay−up Board Design The evaluation board was designed for non−inverting op amp configuration (Figure 2). The input contains termination resistor R3 (usually 50 Ω). The input can also be monitored through J1 when R1 and R2 are populated. The © Semiconductor Components Industries, LLC, 2005 July, 2005 − Rev. 0 evaluation board has versatile loading options for the op amp through C9, R10, and R11 depending on the user’s preference it can be configured as capacitive load, series resistance load, parallel resistance load, etc. 1 Publication Order Number: OPAMP1EVB/D OPAMP1EVB VCC OA Banana Jack J5 GND Banana Jack J7 Ferrite Bead L2 VCC D6 C7 C6 VEE OA Ferrite Bead Banana Jack L1 J6 VEE C5 C3 C2 R7 C1 D7 R5 EN JMP1 BNC Connector Scope J1 BNC Connector IN J2 R1 R2 + − R3 R10 VEE VCC C9 R11 BNC Connector Out J3 R6 R4 Figure 2.
