ADA4851-1/ADA4851-2/ADA4851-4 are low-cost, high-performance, low-power rail-to-rail output op amps suitable for automotive, automotive driver assistance systems, consumer video, professional video, video switchers, active filters and clock buffers applications.
The ADA4851‑2 belongs to the ADA4851 family of voltage‑feedback op‑amps that combine low price with high performance. It offers a 130 MHz (‑3 dB) bandwidth, 375 V/µs slew rate, and rail‑to‑rail output swing within 60 mV of either supply rail. The device is qualified for automotive use and is optimized for consumer and professional video, active filters, clock buffers, and other high‑speed signal‑conditioning tasks.
Available in 6‑lead SOT‑23, 8‑lead MSOP, and 14‑lead TSSOP packages, the ADA4851‑2 operates from a 2.7 V to 12 V supply range, draws only 2.5 mA per amplifier in normal mode, and includes a power‑down mode for low standby current. Detailed specifications, pin configurations, and ordering information are provided throughout the handbook.
