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
Low Offset Voltage: 30µV (Max. @25°C)
Quiescent Current: 180µA per Amplifier

complementary input stages. This design
results in superior performance for driving
analog-to-digital converters (ADCs) without
degradation of differential linearity.
CBM8554 Available in SOP-14 and
TSSOP-14 Packages
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.
