OP492

双/四路，单电源运算放大器 Dual/Quad Single-Supply Operational Amplifiers

Product Details

The OP292/ 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 0.8 mV 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.
