Quad Rail-to-Rail-CMOS-OP, 2,1..5,5V, 0,15MHz, 0,05V/µs, SO-14

DESCRIPTION
The SGM8521 (single), SGM8522 (dual) and SGM8524 (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 SGM8521/2/4 provide 150kHz bandwidth at a low current consumption of 5.5µA per amplifier. Very low input bias currents enable the SGM8521/2/4 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.
They are specified over the extended -40° to +125° temperature range.
