SGM8048 Datasheet, PDF (1/10 Pages) SG Micro Corp – Input/Output Operational Amplifier

SGM8048
690nA, Non-Unity Gain, Quad Rail-to-Rail
Input/Output Operational Amplifier
PRODUCT DESCRIPTION
The SGM8048 operates with a single supply voltage as
low as 1.4V, while drawing less than 690nA (TYP) of
quiescent current per amplifier. This device is also
designed to support rail-to-rail input and output operation.
This combination of features supports battery-powered
and portable applications.
The SGM8048 has a gain-bandwidth product of 100kHz
(TYP) and is stable for gains ≥ 10. The combination of
characteristics makes the SGM8048 ideal for low
frequency applications, such as battery current
monitoring and sensor conditioning.
The SGM8048 operational amplifier is offered in quad
configuration and it is specified for the extended industrial
(-40℃ to +85℃) temperature range. The SGM8048 is
available in the Green SOIC-14, TSSOP-14 packages.
