SGM8040S-1

550nA, Rail-to-Rail I/O,

High Precision Operational Amplifier

GENERAL DESCRIPTION

FEATURES

The SGM8040S-1 is a single, high precision operational

amplifier which can operate from 1.4V to 5.5V single

supply, while consuming only 550nA quiescent current.

It is capable of rail-to-rail input and output. Therefore,

the SGM8040S-1 is suitable for use in portable

instrumentation and battery-powered equipment.

● Low Quiescent Current: 550nA (TYP)

● Low Offset Voltage: 420µV (MAX)

● Unity-Gain Stable

● Gain-Bandwidth Product: 11kHz (TYP)

● Rail-to-Rail Input and Output

● Supply Voltage Range: 1.4V to 5.5V

● -40℃ to +85℃ Operating Temperature Range

● Available in a Green SOT-23-5 Package

The SGM8040S-1 is unity-gain stable, and features an

11kHz gain-bandwidth product. It is designed to provide

optimal performance in low-frequency systems, when

monitoring battery current and conditioning sensor

signal.
