描述 Description

The SGM8240-1 (single), SGM8240-2 (dual) and SGM8240-4 (quad) are micro-power and high voltage operational amplifiers, which are suitable for battery-powered systems. These devices can operate from 2.7V to 24V single supply or from ±1.35V to ±12V dual power supplies, and consume only 2.8μA quiescent current per amplifier. They also provide rail-to-rail input and output operation.
The SGM8240-1/2/4 provide low power, low bias current and low noise. These devices fit in small packages. The combination of the above features makes them appropriate for various applications.
The SGM8240-1 is available in Green SOT-23-5 and SC70-5 packages. The SGM8240-2 is available in Green SOIC-8, MSOP-8 and TDFN-2×3-8L packages. The SGM8240-4 is available in a Green SOIC-14 package. They are specified from -40℃ to +125℃ temperature range.
