The AD8031/AD8032 are low-power, single-supply, rail-to-rail input and output amplifiers with supply voltage ranges of +2.7V to +5V and maximum output current of 15mA. They offer up to 80MHz bandwidth and 125ns settling time. They feature a low output offset voltage (VOS) of 1.5mV and low distortion.
The AD8031 (single) and AD8032 (dual) are single‑supply, voltage‑feedback amplifiers offering rail‑to‑rail input and output, low supply current (800 pA per amplifier) and high speed performance (80 MHz bandwidth, 30 V/µs slew rate). They are specified for +2.7 V, +5 V and +12 V supplies and are suited for battery‑powered, high‑bandwidth applications such as ADC buffers and active filters.
The document provides detailed specifications, absolute maximum ratings, typical performance curves, connection diagrams for multiple package styles (PDIP, SOIC, MSOP, SOT‑23) and an ordering guide that lists all available part numbers and temperature ranges.
