The SGM8049-1 (single), SGM8049-2 (dual) and SGM8049-4 (quad) are low voltage and micro-power operational amplifiers suitable for battery-powered systems.
1.8V, 2.5μA, 120kHz, Rail-to-Rail I/O Operational Amplifier
The SGM8049-1 (single), SGM8049-2 (dual) and SGM8049-4 (quad) are low voltage and micro-power operational amplifiers suitable for battery-powered systems. These devices can operate from 1.8V to 5.5V single supply, while consuming only 2.5μA/Amplifier quiescent current. They also provide rail-to-rail input and output operation.
The SGM8049-1/2/4 provide low power, low bias current and low noise. These devices fit in small packages. The combination of above features makes them appropriate for various applications.
The SGM8049-1 is available in Green SC70-5, SOT-23-5 and TDFN-2×2-6L packages. The SGM8049-2 is available in Green SOT-23-8 and SOIC-8 packages. The SGM8049-4 is available in a Green TSSOP-14 package. They are specified over the extended -40℃ to +125℃ temperature range.
