General Description
The GS804X family has a high gain-bandwidth product of 14.5KHz, a slew rate of 6V/ms, and a quiescent current of
600nA/amplifier at 5V. The GS804X 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 3mV for GS804X family. They are specified over the extended industrial temperature range
packages. The GS8042 Dual is available in Green SOP-8 and MSOP-8 packages. The GS8043 single is available in Green
SC70-6 and SOT23-6 packages.
