MB-9

MicroAmp MB-9 Circuit Board For SOIC-8 Operational Amplifiers FEATURES • Fits standard single SOIC-8 op-amp packages • Inverting or non-inverting configuration • Optional DC blocks on input and output • Uses standard 0603 passives • RO-4350 board material • Fits MicroAmp MH-series housings The MicroAmp MB-9 circuit board is designed for rapid prototyping of operational amplifier circuits using standard pinout SOIC-8 packages. It can be configured as an inverting or non-inverting topology with selectable input and feedback resistors and has a parallel feedback capacitor for filtering or compensation. This board will fit the MicroAmp MH series of connectorized housings that allow it to be used as a single amplifier stage or cascaded with other MicroAmp boards for added versatility. Boards are fabricated from a high-performance 13 mil thick RO-4350 laminate with RoHS compatible ENIG plating (electroless nickel/immersion gold) on both the component side and the solid bottom ground plane. The board measures 0.490" x 0.590" and mounts into the housing with four #1-72 screws. Amplifier circuits can be easily designed and assembled with standard 0603 surface-mount passive components. It includes provisions for input and output DC blocking capacitors, or these can be replaced with zero-ohm jumpers for DC operation. Pads for the input/output connectors allow the SMA center pins to be easily soldered to the board after it is installed into the housing, as well as large pads to connect the bias voltages to feed-throughs. Separate bias pads are provided for single and dual power supply configurations.
