3 Description
The OPA4277-SP precision operational amplifier
replaces the industry standard LM124-SP. The
OPA4277‑SP 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 ±2V to ±18V
supplies with excellent performance. Unlike most
operational amplifiers that 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 ±5V to
±15V 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. The device 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.
