The AD9248 is a dual, 3V, 14-bit, 20 MSPS/40 MSPS/65 MSPS analog-to-digital converter (ADC). It features dual high performance sample-and hold amplifiers (SH) and other characteristics and features.
The AD9248 is a dual, 3 V, 14‑bit analog‑to‑digital converter that supports sample rates of 20, 40 and 65 MSPS. It features dual high‑performance sample‑and‑hold amplifiers, an integrated voltage reference, and a clock‑duty‑cycle stabilizer for reliable operation over a wide range of clock conditions.
The device is supplied in 64‑lead LOFP or LFCSP packages, operates from a 2.7 V to 3.6 V supply, and is rated for industrial temperature ranges (‑45 °C to +85 °C). It is suited for ultrasound equipment, high‑speed oscilloscopes, battery‑powered instruments, and other high‑performance data‑acquisition applications.
