? Low Cost
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.
