OPA4277-SP

SBOS771A –DECEMBER 2016–REVISED JANUARY 2019

OPA4277-SP Radiation Hardened High-Precision Operational Amplifier

The OPA4277-SP operates from ±2- to ±18-V

supplies with excellent performance. Unlike most

operational amplifiers which are specified at only one

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.

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.
