OPAMPEVM-SOIC: OPAMPEVM-SOIC and ACF2101

Part Number: OPAMPEVM-SOIC
Other Parts Discussed in Thread: ACF2101, , IVC102

I need to evaluate an ACF2101 switched integrator. As it's surface mount I'd like to get an evaluation board.

The ACF2101 documentation says it works with the OPAMPEVM-SOIC opamp board, but it has 24 pins

and the board is speced to work with 8 14 and 16 pin chips.......so how do I use it with the ACF2101

or is the TI information wrong? 

Also the original Burr Brown data sheet mentions a fully featured demo board DEM-ACF2101BP-C and it would 

be great to get hold of one of those....is it still available?

    Hello Clive,

    You are correct, the OPAMPEVM-SOIC op amp board will not work with the AFC2101 because it doesn't accommodate 24-pin, 0.3" (7.6 mm) wide packages. Also, I checked on the availability of the DEM-ACF2101BP-C board and found nothing listed in our systems. It was available back in the Burr-Brown days. If the interest in the EVM was low it would have been discontinued.

    We are trying to track down a 24, or 28, pin HSOP to DIP adapter board that could be used to break out the AFC2101. I think we have identified one and have ordered a few to check them. We should have them by tomorrow. I'll let you know what we find about their suitability.

    Thanks, I was going to go with an adapter as I figured the board would not work. I'll stay tuned to see the results of the ones you've ordered. I suppose I could always use the IVC102 and one of your op amp evaluation boards.

    Hello Clive,

     

    The surface mount to DIP adaptor boards that we ordered from Digikey arrived this morning. The ACF2101 fits nicely on the board, and it is very reasonably priced. You can view the board at:

    The IVC102 ha excellent performance as well. It is supported by another TI business unit.
