Hi Jonathan, the National parts are a bit more expensive than the e2V parts:
e2V AT84AD001BCTD ADC Dual Flash 1GSPS 8-Bit Parallel 144-Pin LQFP AT84AD001BCTD e2v 10-$199.2000 25+-$178.8000 National ADC08D1500CIYB 25+ $484.00 High Performance, Low Power, Dual 8-Bit, 1.5 GSPS A/D Converter LQFP EXP PAD 128 -Oren > Thanks for the refresher, Dan.
