Higher dynamic range ADCs

The new 14-bit, 800ksps LTC1419 enhances new communications, spectral analysis, instrumentation and data acquisition applications by providing an upgrade path to users of 12-bit converters. It provides outstanding 81.5dB SINAD (signal-to-noise and distortion ratio) and 95dB SFDR (spurious-free dynamic range) for frequency-domain applications, and excellent DNL with no missing codes performance for time-domain ...
