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 low power, flexible analog input, and clock duty-cycle stabilizer.
The AD9245 from Analog Devices is a monolithic 14‑bit analog‑to‑digital converter that operates from a single 3 V supply. It supports sample rates of 20 MSPS to 80 MSPS, provides a differential input with up to 2 V p‑p range, and includes an on‑chip reference and sample‑and‑hold amplifier.
Designed for medical imaging, communications, and battery‑powered instruments, the device features low power dissipation (90 mW at 20 MSPS up to 366 mW at 80 MSPS) and a wide bandwidth SHA that maintains performance across a range of clock duty cycles.
