SGM8925 110kHz, 6.4μA, Rail-to-Rail Output CMOS Operational Amplifier


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 -40 to +85 temperature range.
