The AD9260 is a 16-bit high-speed oversampled analog-to-digital converter (ADC) with a 16-bit resolution at a 2.5 MHz output word rate. It features an 8× oversampling mode, a 20 MSPS clock, a 1.01 MHz signal passband with 0.004 dB ripple, an 88.5 dB signal-to-noise ratio, -96 dB total harmonic distortion, 100 dB spurious-free dynamic range, 0.6 LSB input referred noise, and other characteristics.
The AD9260 is a 16‑bit, high‑speed oversampling CMOS ADC offering up to a 2.5 MHz output word rate with selectable decimation ratios (1×, 2×, 4×, 8×). It operates from a single +5 V analog supply and provides a differential input range of up to 4 Vpp, with low input‑referred noise and high dynamic range.
The document includes functional block diagrams, detailed electrical specifications, digital filter characteristics, and ordering information. It also provides typical performance curves for each decimation mode and outlines the 44‑lead MQFP package dimensions.
