The ADA4084 series (ADA4084‑1 single‑channel, ADA4084‑2 dual‑channel, ADA4084‑4 quad‑channel) are single‑supply operational amplifiers with a 10 MHz bandwidth, rail‑to‑rail input and output, and low power consumption. They operate from +3 V to +30 V (or ±1.5 V to ±15 V) and are suited for battery‑powered instrumentation, high‑side/low‑side sensing, power‑supply control, telecommunications, DAC output amplification, and ADC input buffering.
The datasheet provides detailed electrical characteristics, absolute maximum ratings, thermal resistance data, pin configurations, typical performance curves, and design notes for low‑noise circuit implementation. Package options include 5‑lead SOT‑23, 8‑lead SOIC, 8‑lead MSOP, 8‑lead LFCSP, 14‑lead TSSOP, and 16‑lead LFCSP. This manual is written in Chinese.
