The SGM8531 (single), SGM8532 (dual) and SGM8534 (quad) are rail-to-rail input and output voltage feedback amplifiers offering low cost. They have a wide input common-mode voltage range and output voltage swing, and take the minimum operating supply voltage down to 2.1V and the maximum recommended supply voltage is 5.5V. All are specified over the extended-40°C to +125°C temperature range.
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 inputs and outputs are useful to designers 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 SGM8531 is available in the tiny SOT-23-5 and SOIC-8 packages. The SGM8532 comes in the miniature SOIC-8 and MSOP-8 packages. The SGM8534 is offered in TSSOP-14 and SOIC-14 packages.
