  SGM8531 Available in SOIC-8 and SOT-23-5

The SGM8531 (single) and SGM8532 (dual) 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. All are specified over the extended -40℃ to +125℃ temperature range. The SGM8531/2 provide 500kHz bandwidth at a low current consumption of 18µA per amplifier. Very low input bias currents of 0.5pA enable the SGM8531/2 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.
