SGM8538 1.5MHz, Rail-to-Rail Output Operational Amplifier

GENERAL DESCRIPTION

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 insingle-supply systems.

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

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