3.3V to 24V, 1MHz, Low Noise, Rail-to-Rail I/O Operational Amplifier
3.3V to 24V, 1MHz, Low Noise, Rail-to-Rail I/O Operational Amplifier

The SGM8210-1, SGM8210-2 and SGM8210-4 low power, wide power supply range operational amplifiers are designed for battery-powered applications. The amplifiers operate with a supply voltage from 3.3V (±1.65V) to 24V (±12V). High-performance, single-supply operation and rail-to-rail capability make the SGM8210-1/2/4 useful for a wide range of applications.

In addition of small packages, the SGM8210-1/2/4 operational amplifiers feature impressive bandwidth, low bias current and low noise relative to the low quiescent current.

The single SGM8210-1 is available in Green SOT-23-5 and SC70-5 packages. The dual SGM8210-2 is available in Green SOIC-8, MSOP-8 and TDFN-2×3-8L packages. The quad SGM8210-4 is available in a Green SOIC-14 package. They are specified over the extended industrial temperature range (-40 to +125).
