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.
