OP292/OP492 are dual/quad single-supply operational amplifiers with features including single-supply operation, input common-mode includes ground, output swings to ground, high slew rate, high gain bandwidth, low input offset voltage, high open-loop gain, and no phase inversion.
The OP292/OP492 series are general‑purpose dual and quad operational amplifiers designed for single‑supply applications, ideal for 5 V systems and battery‑operated instrumentation. They feature a PNP input stage that includes ground in the input range and a BiCMOS output stage that allows the output to swing to ground.
Key performance figures include a typical slew rate of 3 V/µs, a gain‑bandwidth product of 4 MHz, low input offset voltage (0.1‑0.8 mV), and a supply voltage range up to 33 V. The devices operate over an extended temperature range (‑40 °C to +125 °C) and meet stringent ESD protection requirements.
