The CBM833X amplifier is single/dual/quad supply, micro-power, zero-drift CMOS operational amplifiers, the amplifiers offer bandwidth of 350 kHz, rail-to-rail inputs and outputs, and single-supply operation from 1.8V to 5.5V. CBM833X uses chopper stabilized technique to provide very low offset voltage (less than 10µV maximum) and near zero drift over temperature. Low quiescent supply current of 25µA 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 CBM833X 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 CBM8333 is available in SOT23-5, SC70-5 and SOP8 packages. And the CBM8336 is available in SOP8, MSOP8 and DFN-8 packages. The CBM8339 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.
