MicroAmp MB-10 Circuit Board
For 5-pin SOT-23 Operational Amplifiers
FEATURES
• Fits standard 5-pin SOT-23
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-10 circuit board is designed for rapid prototyping of operational amplifier circuits using popular 5-pin SOT-23
packages with the output on pin 1, non-inverting input on pin 3, and the inverting input on pin 4. 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 bias configurations. Use caution on the bias polarity
depending upon the specific op-amp being used.
