Many applications require a precision data acquisition signal chain in order to digitize analog data so that it can be collected and processed accurately. Precision system designers are continually pressed to find innovative ways to improve performance and reduce power dissipation while accommodating increased circuit density in a small PCB footprint.

This paper discusses the common pain points encountered in designing a precision data acquisition signal chain and how to address them using the next generation of 16-/18-bit, 2 MSPS, precision successive approximation register (SAR) ADCs.
