OP492: Quad Single Supply Operational Amplifier
The OP292/OP492 are low cost, general-purpose dual and quad operational amplifiers designed for single-supply applications and are ideal for 5 V systems. Fabricated on Analog Devices, Inc., CBCMOS process, the OP292/OP492 series has a PNP input stage that allows the input voltage range to include ground. A BiCMOS output stage enables the output to swing to ground while sinking current.
The OP292/OP492 series is unity-gain stable and features an outstanding combination of speed and performance for single-or dual-supply operation. The OP292/OP492 provide a high slew rate, high bandwidth, with open-loop gain exceeding 40,000 and offset voltage under 800 Ω (OP292) and 1 mV (OP492). With these combinations of features and low supply current, the OP292/OP492 series is an excellent choice for battery-operated applications. The OP292/OP492 series performance is specified for single- or dual-supply voltage operation over the extended industrial temperature range (−40°C to +125°C).(OP292) and SO-14.
