The GT834X series, which includes single, dual, and quad operational amplifiers, are high-performance, low-power, rail-to-rail input-output, low-voltage operational amplifiers. These amplifiers support single-supply power supplies from 2.2V to 5.5V, as well as dual-supply power supply application scenarios from ±1.1V to ±2.75V, with low quiescent current consumption and input common-mode range support to 0.1V beyond the supply rails.

The GT834X series features a low input mismatch voltage of ±1mV(max) along with a gain bandwidth product of 1.1MHz and a slew rate of 0.4V/us. These features make these operational amplifiers ideal for use in a wide variety of applications such as sensors, audio, active filters, A/D converters, communications, test equipment, cellular and cordless telephones, notebook computers and tablets, photodiode amplification, and battery powered instruments.

Regarding packages, the GT8341 is available in SC70-5, SOT23-5, and SOP-8, MSOP-8 packages.The GT8342 is available in SOP-8, MSOP-8 packages.The GT8344 is available in SOP-14, TSSOP-14 packages.
