SGM8926
110kHz, Rail-to-Rail Output
CMOS Operational Amplifier
PRODUCT DESCRIPTION
The SGM8926 is a low power, low offset voltage and
rail-to-rail output voltage feedback amplifier. It has a wide
output voltage swing, and takes the minimum operating
supply voltage down to 1.6V. The maximum
recommended supply voltage is 5.5V.
The SGM8926 provides 110kHz bandwidth at a low
current consumption of 6.4μA per amplifier. Very low
input bias currents of 1pA enable this amplifier to be
used for integrators, photodiode amplifiers, and
piezoelectric sensors. Rail-to-rail output is useful to
designers for buffering ASIC in single-supply systems.
Applications for this amplifier also include safety
monitoring, portable equipment, battery and power
supply control, signal conditioning and interfacing for
transducers in very low power systems.
The SGM8926 dual is available in Green MSOP-8 and
SOIC-8 packages. It is specified over the extended -40℃
to +85℃ temperature range.
