The document introduces the features and characteristics of Analog Devices OP292/OP492 dual/quad single-supply operational amplifiers, including single-supply range, input common-mode range, output swing, high slew rate, high gain bandwidth, low input offset voltage, high open-loop gain, no phase inversion, low cost, etc.
The OP292 and OP492 are low‑cost, general‑purpose dual and quad operational amplifiers designed for single‑supply applications. They feature a PNP input stage that includes ground in the input range and a BiCMOS output stage that can swing to ground while sinking current.
The devices are unity‑gain stable, offer high slew rate, high gain‑bandwidth product, low offset voltage, and low supply current, making them suitable for battery‑operated instrumentation, mobile phones, disk drives, and other low‑power systems.
| Supply Voltage Range | 4.5 V to 33 V |
|---|---|
| Slew Rate | 3 V/µs |
| Gain‑Bandwidth Product | 4 MHz |
| Package Options | DIP, SO‑8 (OP292) and SO‑14 (OP492) |
They operate from 4.5 V up to 33 V on a single supply.
The OP292 is offered in plastic DIP and SO‑8 packages, while the OP492 is available in DIP and SO‑14 packages.
The typical slew rate is 3 V/µs.
Both devices have a gain‑bandwidth product of 4 MHz.
