GENERAL DESCRIPTION
The single SGM8040-1 and dual SGM8040-2 are
nano-power, high precision operational amplifiers.
These devices can operate from 1.4V to 5.5V single
supply, and consume only 550nA quiescent current per
amplifier. They are capable of rail-to-rail input and
output. Therefore, the SGM8040-1/2 are suitable for
use in portable instrumentation and battery-powered
equipment.
The SGM8040-1/2 are unity-gain stable, and feature an
11kHz gain-bandwidth product. They are designed to
provide optimal performance in low-frequency systems,
when monitoring battery current and conditioning sensor
signal.
The SGM8040-1 is available in Green SOT-23-5,
SC70-5 and SOIC-8 packages. The SGM8040-2 is
available in Green SOIC-8 and TDFN-2×2-8L packages.
They operate over an ambient temperature range of
-40℃ to +85℃.
