Analog Devices ADA4939-1/ADA4939-2 Datasheet
The ADA4939 family provides ultralow harmonic distortion, high‑speed differential amplification, and single‑supply operation (3.3 V to 5 V). Features include adjustable gain, adjustable output common‑mode voltage, and fast over‑drive recovery (<1 ns). The devices are optimized for driving high‑performance ADCs up to 16‑bit resolution.
The datasheet details electrical specifications, pin configurations, thermal characteristics, and application examples such as single‑ended‑to‑differential conversion and broadband ADC driving. Ordering information and mechanical dimensions for the 16‑lead and 24‑lead LFCSP packages are also provided.
