The AD8628/AD8629/AD8630 are wide bandwidth auto-zero amplifiers featuring rail-to-rail input and output swing and low noise.
The AD8628, AD8629, and AD8630 are zero‑drift, single‑supply operational amplifiers with rail‑to‑rail input and output swing. They offer ultra‑low offset (1 µV min, 5 µV typ), low bias current (30 pA‑100 pA), and low supply current, making them suitable for automotive sensors, pressure and position sensors, strain‑gage amplifiers, medical instrumentation, thermocouple amplifiers, precision current sensing, and photodiode amplifiers.
The document includes detailed electrical characteristics for both 5 V and 2.7 V supply options, absolute maximum ratings, thermal data, ESD precautions, typical performance graphs, and an ordering guide that lists the available TSOT, SOT‑23, SOIC, MSOP, and TSSOP packages.
