SGM8038-1/SGM8038-2

6µA, 145kHz, Rail-to-Rail I/O,

High Precision Operational Amplifiers

GENERAL DESCRIPTION

FEATURES

The single SGM8038-1 and dual SGM8038-2 are high

precision operational amplifiers which can operate from

1.4V to 5.5V single supply, while consuming only 6µA

quiescent current per amplifier. They are capable of

rail-to-rail input and output. Therefore, the SGM8038-1/2

are suitable for use in portable instrumentation and

battery-powered equipment.

● Low Quiescent Current: 6µA/Amplifier (TYP)

● Low Offset Voltage: 800µV (MAX) at V_S= 5V

● Unity-Gain Stable

● Gain-Bandwidth Product: 145kHz (TYP) at V_S= 5V

● Rail-to-Rail Input and Output

● Supply Voltage Range: 1.4V to 5.5V

● -40℃ to +125℃ Operating Temperature Range

● Small Packaging:

The SGM8038-1/2 are unity-gain stable, and feature a

145kHz gain-bandwidth product. They are designed to

provide optimal performance in low-frequency systems,

when monitoring battery current and conditioning sensor

signal.

SGM8038-1 Available in Green SOT-23-5, SC70-5

and SOIC-8 Packages

SGM8038-2 Available in Green SOT-23-8, SOIC-8

and TDFN-2×2-8L Packages

The SGM8038-1 is available in Green SOT-23-5,

SC70-5 and SOIC-8 packages. The SGM8038-2 is

available in Green SOT-23-8, SOIC-8 and TDFN-2×2-8L
