GENERAL DEscriptION

The SGM80581 (single), SGM80582 (dual) and SGM80584 (quad) are high speed operational amplifiers with voltage feedback function. These devices can operate from 2.5V to 5.5V single supply or from ±1.25V to ±2.75V dual supplies while consuming only 4.5mA current per amplifier.

The SGM80581/2/4 support rail-to-rail input and output operation. They have a wide input common mode voltage range and output swing within 15mV. The multi-channel version has a completely independent circuit to achieve minimum crosstalk and no interaction.

The SGM80581/2/4 feature a differential phase of 0.1° and a differential gain of 0.01%, which are designed to provide excellent video performance. They have a 220MHz wide bandwidth and are unity-gain stable. These devices also have high output drive capability. The SGM80581/2/4 are well suited for a wide range of applications.

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 specified over the extended -40℃ to +125℃ temperature range
