GENERAL DEscriptION

The SGM321XC5 is a single, low cost, voltage feedback amplifier. The device can operate from 2.1V to 5.5V single supply, while consuming only 60μA 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 SGM321XC5 appropriate for buffering ASIC.

The SGM321XC5 offers a gain-bandwidth product of 1MHz and an ultra-low input bias current of 10pA. It is well suited for piezoelectric sensors, integrators and photodiode amplifiers.

The SGM321XC5 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 SGM321XC5 is available in a Green SC70-5 package. It is specified over the extended -40℃ to +125℃ temperature range.
