描述 Description

The SGM8925 (single) and SGM8927 (single with shutdown) are low offset voltage, low power, voltage feedback amplifiers. These devices can operate from 1.6V to 5.5V single supply, and consume only 6.4μA quiescent current. They provide a wide input common mode voltage range and rail-to-rail output voltage swing. This feature makes SGM8925/7 appropriate for buffering ASIC.
The SGM8925/7 offer a gain-bandwidth product of 100kHz and an ultra-low input bias current of 1pA. They are well suited for piezoelectric sensors, integrators and photodiode amplifiers.
The SGM8925/7 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 SGM8925 is available in Green SOT-23-5, SC70-5, MSOP-8 and SOIC-8 packages. The SGM8927 is available in Green SOT-23-6, MSOP-8 and SOIC-8 packages. They are specified over the extended -40℃?to +85℃?temperature range.
