GENERAL DESCRIPTION
The AD13280 is a complete, dual-channel, signal processing solution that includes on-board amplifiers, references, ADCs, and output termination components to provide optimized system performance. The AD13280 has on-chip track-and-hold circuitry and uses an innovative multipass architecture to achieve 12-bit, 80 MSPS performance. The AD13280 uses innovative high density circuit design and laser-trimmed thin-film resistor networks to achieve exceptional channel matching, impedance control, and performance while maintaining excellent isolation and providing for significant board area savings.
