The ADA4500-2 Eliminates Crossover Distortion Across its Full Supply Range 5 10617-004 GENERAL DESCRIPTION The ADA4500-2 is a dual 10 MHz, 14.5 nV/√Hz, low power amplifier featuring rail-to-rail input and output swings while operating from a 2.7 V to 5.5 V single power supply. Compatible with industry-standard nominal voltages of +3.0 V, +3.3 V, +5.0 V, and ±2.5 V. Employing a novel zero-crossover distortion circuit topology, this amplifier offers high linearity over the full, rail-to-rail input c...
