General Description
The GS321A/358A family have a high gain-bandwidth product of 1MHz, a slew rate of 0.6V/µs, and a quiescent current of
40µA/amplifier at 5V. The GS321A/358A family is designed to provide optimal performance in low voltage and low noise
systems. They provide rail-to-rail output swing into heavy loads. The input common mode voltage range includes ground, and
the maximum input offset voltage is 0.5mV for GS321A/358A family. They are specified over the extended industrial
SC70-5 and SOT23-5 packages. The GS358A Dual is available in Green SOP-8 and MSOP-8 packages.
