AD8691/AD8692/AD8694 Low Cost, Low Noise, CMOS Rail-to-Rail Output Operational Amplifiers
The AD8691, AD8692, and AD8694 are low‑cost, low‑noise CMOS rail‑to‑rail output operational amplifiers designed for applications such as photodiode amplification, battery‑powered instrumentation, medical instruments, sensors, and portable audio devices. Their low offset voltage, low bias current, and wide bandwidth make them suitable for high‑precision and high‑speed circuits.
The handbook includes detailed electrical characteristics, absolute maximum ratings, thermal data, pin‑out diagrams, typical performance graphs, and an ordering guide for the various package options (TSOT, SC70, MSOP, SOIC, TSSOP). It also lists the operating temperature range and supply voltage specifications required for reliable operation.
| Low Noise | 8 nV/√Hz |
|---|---|
| Gain Bandwidth Product | 10 MHz |
| Supply Voltage Range | 2.7 V to 6 V |
| Operating Temperature Range | -40 °C to +125 °C |
They operate from 2.7 V up to 6 V on a single supply.
The gain‑bandwidth product is 10 MHz.
