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 line driver. 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, consuming 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.
