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) These units are intended for engineering evaluation only.  
They are processed to a noncompliant flow. These units are  
not suitable for qualification, production, radiation testing or  
flight use. Parts are not warrantied for performance over the  
full MIL specified temperature range of –55°C to 125°C or  
operating life.

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.
