Overview
The AD9260AS, produced by Analog Devices Inc., is a 16-bit, high-speed oversampled analog-to-digital converter (ADC) that offers exceptional dynamic range over a wide bandwidth. Manufactured on an advanced CMOS process, this ADC combines the advantages of sigma-delta and pipeline converter technologies to achieve high dynamic range. It features a nominal full-scale input range of 4 V with differential inputs and 60 dB of common-mode rejection. The AD9260AS operates on a single +5 V supply and includes a power scaling circuit to adjust power consumption between 150 mW and 585 mW.
