SGM8524
150kHz, 5.5μA, Rail-to-Rail I/O, CMOS Operational Amplifier
150kHz, 5.5μA, Rail-to-Rail I/O, CMOS Operational Amplifier
GENERAL DESCRIPTION

The SGM8521 (single), SGM8522 (dual) and SGM8524 (quad) are low cost, voltage feedback amplifiers. These devices can operate from 2.1V to 5.5V single supply, while consuming only 5.5μA 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 SGM8521/2/4 appropriate for buffering ASIC.

The SGM8521/2/4 offer a gain-bandwidth product of 150kHz and an ultra-low input bias current of 3pA. They are well suited for piezoelectric sensors, integrators and photodiode amplifiers.

The SGM8521/2/4 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 SGM8521 is available in Green SOT-23-5 and SOIC-8 packages. The SGM8522 is available in Green SOIC-8 and MSOP-8 packages. The SGM8524 is available in Green SOIC-14 and TSSOP-14 packages. They are specified over the extended -40 to +125 temperature range.
