Needs to be 8pin DIP LTC's LT1206 comes in TO220, miniDIP and soic packages, and Digi-Key has them in stock for $6.25 each... http://rocky.digikey.com/WebLib/Line...ata/LT1206.pdf http://www.digikey.com/scripts/DkSea...ail?Ref=329191 and operate on a single-ended supply. Oops, +/-5V supply. What's your signal voltage? And did you want your output to have a 50-ohm source impedance? Maybe an LT1191? digikey #: LT1191CN8-ND (24 in stock at USD 3.25) http://rocky.digikey.com/WebLib/Line...ata/LT1191.pdf --Mac |
