    The CBM855X amplifier is single/dual/quad supply,micro-power,zero-drift CMOS operational amplifiers, the amplifiers offer bandwidth of 1.8MHz, rail-to-rail inputs and outputs, and single-supply operation from 1.8V to 5.5V. CBM855X uses chopper stabilized technique to provide very low offset voltage (less than 5µV maximum) and near zero drift over temperature. Low quiescent supply current of 180µA 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 CBM855X 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 CBM8551 is available in SOT23-5 and SOP-8 packages. And the CBM8552 is available in MSOP-8 and SOP-8 packages. The CBM8554 Quad is available in Green SOP-14 and TSSOP-14 packages. The extended temperature range of -45℃ to +125℃ over all supply voltages offers additional design flexibility.
