Gainsil GS8591-TR

The GS859X amplifier is single/dual/quad supply, micro-power, zero-drift CMOS operational amplifiers, the amplifiers offer bandwidth of 4.5MHz, rail-to-rail inputs and outputs, and single-supply operation from 1.8V to 5.5V. GS859X uses chopper stabilized technique to provide very low offset voltage (less than 30μv maximum) and near zero drift over temperature. Low quiescent supply current of 550μA per amplifier and very low input bias current of 20pA make the devices an ideal choice for low offset, low power consumption and high impedance applications. The GS859X offers excellent CMRR without the crossover associated with traditional complementary input stages. This design results in superior performance for driving analog-to-digital converters (ADCs) without degradation of differential linearity. The GS8591 is available in SOT23-5 and SOP-8 packages. And the GS8592 is available in MSOP-8 and SOP-8 packages. The GS8594 Quad is available in Green SOP-14 and TSSOP-14 packages. The extended temperature range of -45°C to +125°C over all supply voltages offers additional design flexibility.
