SGM8534

GENERAL DESCRIPTION

The SGM8531 (single), SGM8532 (dual) and SGM8534 (quad) are low cost, rail-to-rail input and 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 2.1V. The maximum recommended supply voltage is 5.5V.

The SGM8531/2/4 provide 500kHz bandwidth at a low current consumption of 18μA per amplifier. Very low input bias currents of 0.5pA enable the SGM8531/2/4 to be used for integrators, photodiode amplifiers and piezoelectric sensors. Rail-to-rail input and output 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, and signal conditioning and interfacing for transducers in very low power systems.

The single SGM8531 is available in Green SOT-23-5 and SOIC-8 packages. The dual SGM8532 is available in Green SOIC-8 and MSOP-8 packages. The quad SGM8534 is available in Green SOIC-14 and TSSOP-14 packages. They are specified over the extended -40 to +125temperature range.
