SGM8927 fiche technique
SGM8925/7
110kHz, 6.4μA, Rail-to-Rail Output
CMOS Operational Amplifiers
PRODUCT DESCRIPTION
The SGM8925 and SGM8927 are low power, low offset
voltage and rail-to-rail output voltage feedback amplifiers.
They have a wide output voltage swing, and take the
minimum operating supply voltage down to 1.6V. The
maximum recommended supply voltage is 5.5V.
The SGM8925 and SGM8927 provide 110kHz bandwidth
at a low current consumption of 6.4μA. Very low input
bias currents of 1pA enable these amplifiers 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 these amplifiers also include safety
monitoring, portable equipment, battery and power
supply control, signal conditioning and interfacing for
transducers in very low power systems.
The SGM8925 single is available in Green SOT-23-5,
SC70-5, MSOP-8 and SOIC-8 packages. The SGM8927
single with shutdown is available in Green SOT-23-6,
MSOP-8 and SOIC-8 packages. They are specified over
the extended -40to +85temperature range.
