OPA2107
Precision Dual
OPERATIONAL AMPLIFIER
FEATURES
● VERY LOW NOISE: 8nV/√Hz at 10kHz
● LOW V
● LOW DRIFT: 10µV/
● LOW I
● FAST SETTLING TIME: 2µs to 0.01%
● UNITY-GAIN STABLE
DESCRIPTION
The OPA2107 dual operational amplifier provides
precision
savings of a dual op amp. It is useful in a wide range
of precision and low-noise analog circuitry and can be
used to upgrade the performance of designs currently
using BIFET® type amplifiers.
The OPA2107 is fabricated on a proprietary
dielectrically isolated (
put bias currents to very low levels without sacrificing
other important parameters, such as input offset voltage, drift and noise. Laser-trimmed input circuitry
yields excellent DC performance. Superior dynamic
performance is achieved, yet quiescent current is held
to under 2.5mA per amplifier. The OPA2107 is unitygain stable.
The OPA2107 is available in plastic DIP and SOIC
packages. Industrial temperature range versions are
available.

ELECTROSTATIC
DISCHARGE SENSITIVITY
This integrated circuit can be damaged by ESD. Burr-Brown
recommends that all integrated circuits be handled with
appropriate precautions. Failure to observe proper handling
and installation procedures can cause damage.
ESD damage can range from subtle performance degradation
to complete device failure. Precision integrated circuits may
be more susceptible to damage because very small parametric
changes could cause the device not to meet its published
specifications.
