    The SGM8535 (single), SGM8536 (dual), SGM8537 (single with shutdown) and SGM8538 (quad) are rail-to-rail output voltage feedback amplifiers. They have a wide input common mode voltage range and output voltage swing, and take the minimum operating supply voltage down to 1.8V. The maximum recommended supply voltage is 5.5V.

    The SGM8535/6/7/8 provide 1.5MHz bandwidth at a low current consumption of 80μA per amplifier. Very low input bias currents enable SGM8535/6/7/8 to be used for integrators, photodiode amplifiers and piezoelectric sensors. Rail-to-rail outputs are useful to designers for buffering ASIC in single-supply systems.

    Applications for these amplifiers include safety monitoring, portable equipment, battery and power supply control, signal conditioning and interfacing for transducers in very low power systems.

    The SGM8535/6/7/8 are specified over the -40 to +85 temperature range. The single SGM8535 is available in Green SOT-23-5, SC70-5, MSOP-8 and SOIC-8 packages. The dual SGM8536 is available in Green MSOP-8 and SOIC-8 packages. The single with shutdown SGM8537 is available in Green SOT-23-6, MSOP-8 and SOIC-8 packages. The quad SGM8538 is available in Green SOIC-14 and TSSOP-14 packages.
