3 Description
The OPA4277-SP precision operational amplifier
replaces the industry standard LM124-SP. It offers
improved noise and two orders of magnitude lower
input offset voltage. Features include ultra-low offset
voltage and drift, low-bias current, high common-
mode rejection, and high-power supply rejection.
The OPA4277-SP operates from ±2- to ±18-V
supplies with excellent performance. Unlike most
operational amplifiers which are specified at only one
supply voltage, the OPA4277-SP precision
operational amplifier is specified for real-world
applications; a single limit applies over the ±5- to ±15-
V supply range. High performance is maintained as
the amplifier swings to the specified limits.
The OPA4277-SP is easy to use and free from phase
inversion and overload problems found in some
operational amplifiers. It is stable in unity gain and
provides excellent dynamic behavior over a wide
range of load conditions. The OPA4277-SP features
completely independent circuitry for lowest crosstalk
and freedom from interaction, even when overdriven
or overloaded.
