SGM8045
710nA, Non-Unity Gain, Single Rail-to-Rail
Input/Output Operational Amplifier
PRODUCT DESCRIPTION
The SGM8045 operates with a single supply voltage as
low as 1.4V, while drawing less than 710nA (TYP) of
quiescent current. 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 SGM8045 has a gain-bandwidth product of 100kHz
(TYP) and is stable for gains ≥ 10. The combination of
characteristics makes the SGM8045 ideal for low
frequency applications, such as battery current
monitoring and sensor conditioning.
The SGM8045 operational amplifier is offered in single
configuration and it is specified for the extended industrial
(-40℃ to +85℃) temperature range. The SGM8045 is
available in the Green SOT-23-5, SOIC-8 and MSOP-8
packages.
