Hello! I am working with ECHELON NEURON CHIP and in my configuration I am using A/D converter TLV2544 made by TEXAS and D/A converter TLV5604 olso made by TEXAS. This two chips are available only in SMD tehnology and I am not satisfied with that fact so I need other alternative - normal chip (DIL). Can anyone tell me which substitute can I use. Substitute chip must have serial interface! THANK YOU!! DEJAN
