The AD9245 is a monolithic, single 3 V supply, 14-bit, 20 MSPS/40 MSPS/65 MSPS/80 MSPS analog-to-digital converter (ADC) featuring:
The AD9245 is a monolithic 14‑bit analog‑to‑digital converter that operates from a single 3 V supply (2.7 V to 3.6 V) and offers sampling rates from 20 MSPS up to 80 MSPS. It features a high‑performance sample‑and‑hold amplifier, on‑chip reference, and a differential input bandwidth of 500 MHz, making it suitable for medical imaging, communications, and power‑sensitive military applications.
The datasheet provides full electrical specifications, pin configurations, functional block diagrams, and performance graphs. It also includes application notes on clock input considerations, power dissipation, and evaluation board usage, helping designers integrate the AD9245 into multiplexed or single‑channel systems.
