描述 Description

The SGM8277-1/2 are a family of single and dual operational amplifiers, which are optimized for high voltage, high precision, low noise and low power operation. These devices can operate from 4V to 36V single supply or from ±2V to ±18V dual power supplies, and consume 1100μA quiescent current per amplifier. The input common mode voltage range is from (-VS) + 2V to (+VS) - 2V, and the output swing is rail-to-rail with heavy loads. The SGM8277-1/2 feature a low input offset voltage of ±10μV (TYP) and a low input bias current of ±10pA (TYP). They exhibit a gain-bandwidth product of 4MHz and a slew rate of 3.5V/μs. They are designed to provide optimal performance in low noise systems. These specifications make the operational amplifiers appropriate for various applications. The SGM8277-1 is available in Green SOIC-8 and TDFN-3×3-8L packages. The SGM8277-2 is available in Green SOIC-8, MSOP-8 and TDFN-3×3-8L packages. They are specified over the extended industrial temperature range (-40℃ to +125℃).
