3 Description
The OPA4277-EP precision operational amplifier
replaces the industry standard OP-177. It offers
improved noise, wider output voltage swing, and is
twice as fast with half the quiescent current. Features
include ultra-low offset voltage and drift, low bias
current, high common-mode rejection, and high
power supply rejection.
The OPA4277-EP operates from ±2- to ±18-V
supplies with excellent performance. Unlike most
operational amplifiers which are specified at only one
supply voltage, the OPA4277-EP 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. Because
the initial offset voltage (±20-μV max) is so low, user
adjustment is usually not required.
The OPA4277-EP 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-EP features
completely independent circuitry for lowest crosstalk
and freedom from interaction, even when overdriven
or overloaded.
