DEM-OPA-SOT-1A

The DEM-OPA-SOT-1A demonstration fixture is a generic, unpopulated printed circuit board (PCB) designed to provide an optimised layout when evaluating wideband operational amplifiers in the tiny SOT-23 package only a few components are necessary to be assembled onto the board to set up the operational amplifier in either an inverting or noninverting configuration. In order to avoid parasitic component inductance the board only accepts surface mount resistors and capacitors. The actual values of the components, especially the resistors, depend on the type of operational amplifier used and the intended mode of operation. The board was designed to accommodate a variety of amplifiers voltage feedback types or current feedback types. Furthermore, the evaluation board not only handles op amps in the existing five lead SOT-23 package but also the evaluation platform for six lead SOT-23 package.

• This demonstration fixture is a two layer PCB with the power traces on the bottom layer
• It is designed to operate in 50R environment
• It is easy to change the component values for different input and output impedance levels
• Mid layer one has only power traces, mid layer 2 has both ground and power traces
