GENERAL DEscriptION
The SGM8535 (single), SGM8536 (dual), SGM8537 (single with shutdown) and SGM8538 (quad) are voltage feedback amplifiers. These devices can operate from 1.8V to 5.5V single supply, while consuming only 80μA quiescent current per amplifier. They provide a wide input common mode voltage range and rail-to-rail output voltage swing. This feature makes SGM8535/6/7/8 appropriate for buffering ASIC.
The SGM8535/6/7/8 offer a gain-bandwidth product of 1.5MHz and an ultra-low input bias current of 3pA. They are well suited for piezoelectric sensors, integrators and photodiode amplifiers.
The SGM8535/6/7/8 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 SGM8535 is available in Green SOT-23-5, SC70-5, MSOP-8 and SOIC-8 packages. The SGM8536 is available in Green MSOP-8 and SOIC-8 packages. The SGM8537 is available in Green SOT-23-6, MSOP-8 and SOIC-8 packages. The SGM8538 is available in Green SOIC-14 and TSSOP-14 packages. They are specified over the -40℃ to +85℃ temperature range.
