8-pin MSOP Dual Op Amp Evaluation Board Part Number CLC730123 June 2001 The CLC730123 evaluation board is designed to aid in the characterization of National's 8-pin Dual Op Amps in MSOP package. This board uses all surface-mount components for maximum speed and performance. Figure 1 shows the schematic: VC C + + C3 OUTPUT 1 C4 R14 R17 R4 R19 R15 R13 INPUT 1 R18 1 R1 2 R12 3 OUT A V + V ID- A OUT B V ID+ A V ID- B 4 8 V - 5 V ID+ B R16 R20 7 6 R11 R3 OUTPUT 2 R6 R7 R8 INPUT 2 R9 R10 VCC- C2 C1 + Figure 1: Complete Evaluation Board Schematic This board is designed with versatility in mind; that is, by selective insertion of components, the device can be put into an inverting, or non-inverting configuration. De-coupling caps are essential to be installed for good high frequency behavior, 0.1F and 6.8F are good values in most cases. Note that C2, and C4 are polar caps. Use Tantalum capacitors for lowest ESR. 2001 National Semiconductor Corporation www.national.com Top Side Bottom Side 2001 National Semiconductor Corporation 2 www.national.com LIFE SUPPORT POLICY NATIONAL'S PRODUCTS ARE NOT AUTHORIZED FOR USE AS CRITICAL COMPONENTS IN LIFE SUPPORT DEVICES OR SYSTEMS WITHOUT THE EXPRESS WRITTENT APPROVAL OF THE PRESIDENT AND GENERAL COUNSEL OF NATIONAL SEMICONDUCTOR CORPORATION.
