SGM8142
350nA, Dual Rail-to-Rail I/O
Operational Amplifier
GENERAL DESCRIPTION
FEATURES
● Low Quiescent Current: 350nA/Amplifier (TYP)
● Rail-to-Rail Input and Output
● Gain-Bandwidth Product: 5kHz at VS = 5V (TYP)
● Wide Supply Voltage Range: 1.4V to 5.5V
● Unity-Gain Stable
The SGM8142 is a dual, high precision operational
amplifier which can operate from 1.4V to 5.5V single
supply, while consuming only 350nA/amplifier quiescent
current. It provides rail-to-rail input and output operation.
Therefore, the SGM8142 is suitable for use in portable
instrumentation and battery-powered systems.
● -40℃ to +85℃ Operating Temperature Range
● Available in Green SOIC-8 and MSOP-8 Packages
The SGM8142 is unity-gain stable, and features a 5kHz
gain-bandwidth product. It is designed to provide
optimal performance in low frequency systems, when
monitoring battery current and conditioning sensor
signal.
