SGM8142

350nA, Dual Rail-to-Rail I/O

Operational Amplifier

 

PRODUCT DESCRIPTION

The SGM8142 is guaranteed to operate with a single

supply voltage as low as 1.4V, while drawing less than

350nA (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 SGM8142 has a gain-bandwidth product of 5kHz

(TYP) and is unity gain stable. These specifications

make this operational amplifier appropriate for low

frequency

applications,

such

as

battery

current

monitoring and sensor conditioning.

The SGM8142 is offered in dual configuration. It is

specified for the extended industrial (-40

℃ to +85℃)

temperature range. The SGM8142 is available in the

Green SOIC-8 and MSOP-8 packages.
