GS8591/8592/8594 4.5MHZ Zero-Drift CMOS Rail-to-Rail IO Opamp with RF Filter Features Single-Supply Operation from +1.8V ~ +5.5V Embedded RF Anti-EMI Filter Rail-to-Rail Input / Output Small Package: Gain-Bandwidth Product: 4.5MHz (Typ 25C) GS8591 Available in SOT23-5 and SOP-8 Packages Low Input Bias Current: 20pA (Typ 25C) GS8592 Available in MSOP-8 and SOP-8 Packages Low Offset Voltage: 30V (Max 25C) GS8594 Available in SOP-14 and TSSOP-14 Packages Quiescent Current: 550A per Amplifier (Typ) Operating Temperature: -45C ~ +125C o Zero Drift: 0.01V/ C (Typ) General Description 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 30V maximum) and near zero drift over temperature. Low quiescent supply current of 550A 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 o o 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.
