HT8551 Datasheet | HTCSEMI

Description The HT855X 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. HT855X 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 20p A make the devices an ideal choice for low offset, low power consumption and high impedance applications. The HT855X offers excellent CMRR without the crossover associated with traditional plementary input stages. This design results in superior performance for driving analog-to-digital converters (ADCs) without degradation of differential linearity. The HT8551 is available in SOT23-5 and SOP-8 packages. And the HT8552 is available in MSOP-8 and SOP-8 packages. The HT8554 Quad is available in Green SOP-14 and TSSOP-14 packages. The extended temperature range of -45o C to +125o C over all supply voltages offers additional design flexibility.
