SGM8531
500kHz, 18µA, Rail-to-Rail I/O, CMOS Operational Amplifier
500kHz, 18µA, Rail-to-Rail I/O, CMOS Operational Amplifier
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.

The SGM8531/2/4 are designed into a wide range of applications, such as battery-powered instrumentation, safety monitoring, portable systems, and transducer interface circuits in low power systems.

The SGM8531 is available in Green SOT-23-5 and SOIC-8 packages. The SGM8532 is available in Green SOIC-8 and MSOP-8 packages. The SGM8534 is available in Green SOIC-14 and TSSOP-14 packages. They are specified over the extended -40 to +125 temperature range.
