The SGM80581 (single), SGM80582 (dual) and SGM80584 (quad) are voltage feedback CMOS operational amplifiers, which are optimized for high speed operation. These devices are designed for applications requiring wide bandwidth or high continuous output current, such as video, etc. They can offer a high output current of 150mA. They are unity-gain stable and offer a wide bandwidth of 220MHz. They exhibit a differential gain of 0.01% and a differential phase of 0.1°.
The SGM80581/2/4 can operate from 2.5V to 5.5V single supply or ±1.25V to ±2.75V dual power supplies, and consume 4.5mA quiescent current per amplifier. These devices support rail-to-rail input and output operation. The input common mode voltage range is from (-VS) - 0.1V to (+VS) + 0.1V, and the output range is from (-VS) + 0.015V to (+VS) - 0.015V. The circuitry of multichannel versions is fully independent, which minimizes crosstalk and avoids interaction.
The SGM80581 is available in Green SOT-23-5 and SOIC-8 packages. The SGM80582 is available in Green MSOP-8 and SOIC-8 packages. The SGM80584 is available in a Green SOIC-14 package. They are rated over the extended -40℃ to +125℃ temperature range.
