The SGM321 (single), SGM358 (dual) and SGM324 (quad) are low cost, voltage feedback amplifiers. These devices can operate from 2.1V to 5.5V single supply, and consume only 60μA 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 SGM321/358/324 appropriate for buffering ASIC. 

The SGM321/358/324 offer a gain-bandwidth product of 1MHz and an ultra-low input bias current of 10pA. They are well suited for piezoelectric sensors, integrators and photodiode amplifiers. 

The SGM321/358/324 are designedintoawide range of applications, such as battery-powered instrumentation, safety monitoring, portable systems, and transducer interface circuits in low power systems. 

The SGM321 is available in Green SOT-23-5 and SC70-5 packages. The SGM358 is available in Green SOIC-8, MSOP-8 and DIP-8 packages. The SGM324 is available in Green TSSOP-14 and SOIC-14 packages. They are specified over the extended industrial temperature range (-40℃ to +85℃).
