GENERAL DEscriptION
The SGM8543 (single with shutdown) is a low cost, voltage feedback amplifier. The device can operate from 2.1V to 5.5V single supply, while consuming only 48μA quiescent current. It provides rail-to-rail input with a wide input common mode voltage range and rail-to-rail output voltage swing. This feature makes SGM8543 appropriate for buffering ASIC.
The SGM8543 offers a gain-bandwidth product of 1.1MHz and an ultra-low input bias current of 0.5pA. It is well suited for piezoelectric sensors, integrators and photodiode amplifiers.
The SGM8543 is 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 SGM8543 is available in Green SOIC-8 and SOT-23-6 packages. It is specified over the extended -40℃ to +125℃ temperature range.
