SGM8531/SGM8532/SGM8534 500kHz, 18μA, Rail-to-Rail I/O, CMOS Operational Amplifiers GENERAL DESCRIPTION The SGM8531 (single), SGM8532 (dual) and SGM8534 (quad) are low cost, voltage feedback amplifiers. These devices can operate from 2.1V to 5.5V single supply, while consuming only 18μA quiescent current per amplifier. They provide rail-to-rail input with a wide input common mode voltage range and rail-to-rail output voltage swing. This feature makes SGM8531/2/4 appropriate for buffering ASIC. The SGM8531/2/4 offer a gain-bandwidth product of 500kHz and an ultra-low input bias current of 0.5pA. They are well suited for piezoelectric sensors, integrators and photodiode amplifiers.
