App note from Maxim Integrated about simple fixes that can solve most issues when designing with ASICs. Link here (PDF)
Noise is a common problem in mixed-signal ASICs, degrading performance and jeopardizing the completion of products. This application note gives hints and tips for adding external circuits that make many of these ASICs operational for prototyping or shippable as final products. Ways to optimize the ASIC by correcting noise in analog circuits, making adjustments, calibrating gain and offset, and cleaning power sources are discussed. The payoff is quicker time to market and even the prevention of an extra ASIC manufacturing spin.
