Firefox 0 Report post Posted June 13, 2003 Yup. Clone PPA actually. Unlike the original one that requires 12 buffers. Mine only 3. Adding I use OPA134PA instead of the recommend AD8610. Sadly, that's probably not going to sound as good as PPL probably meant it to sound. The 4 * buffers in each channel is meant to reduce the output impedance. I think you should use at least OPA132's; Their at least better than the OPA134. Of course, you can also request samples for the BB OPA637BP's from TI. Extremely nice chips.
