AD7677:  16-Bit, 1 LSB INL, 1 MSPS Differential PulSAR® ADC

Product Details

The AD7677 is a 16-bit, 1 MSPS, 1 LSB INL, charge redistribution SAR, fully differential analog-to-digital converter that operates from a single 5 V power supply. The AD7677 is the flagship part of the new PulSAR™ family - simultaneously being the fastest as well as the industry's most accurate 16-bit SAR ADC ever introduced . The part contains a high-speed 16-bit sampling ADC, an internal conversion clock, error correction circuits, and both serial and parallel system interface ports.
