Overview
The AD9260ASZ, produced by Analog Devices Inc., is a high-performance 16-bit analog-to-digital converter (ADC) designed for applications requiring exceptional dynamic range and wide bandwidth. This monolithic ADC combines the advantages of sigma-delta and pipeline converter technologies to achieve high dynamic range through an oversampling ratio of up to 8×. It is manufactured on an advanced CMOS process and features a nominal full-scale input range of 4 V with differential inputs. The AD9260ASZ operates on a single +5 V analog supply and can also accommodate a +3 V digital supply, simplifying system power supply design.
