  SGM321 Available in SOT-23-5 and SC70-5

The SGM321 (single), SGM358 (dual) and SGM324 (quad) are low cost, rail-to-rail input and output voltage feedback amplifiers. They have a wide input common mode voltage range and output voltage swing, and take the minimum operating supply voltage down to 2.1V. The maximum recommended supply voltage is 5.5V. All are specified over the extended -40℃ to +85℃ temperature range.

The SGM321/358/324 provide 1MHz bandwidth at a low current consumption of 60μA per amplifier. Very low input bias currents of 10pA enable SGM321/358/324 to be used for integrators, photodiode amplifiers, and piezoelectric sensors. Rail-to-rail input and output are useful to designers for buffering ASIC in single-supply systems.The SGM321 is available in the Green SOT-23-5 and SC70-5 packages.
