OPA377AIDCKR Low-Cost Low-Noise 5.5MHz CMOS Operational Amplifier Integrated Circuit Chip

The OPA377 family of operational amplifiers are wide-bandwidth CMOS amplifiers that provide very low noise, low input bias current, and low offset voltage while operating on a low quiescent current of 0.76mA (typical).

These op amps are optimized for low-voltage, single-supply applications. The exceptional combination of AC and DC performance makes them ideal for a wide range of applications, including small signal conditioning, audio, and active filters. Additionally, these parts have a wide supply range with excellent PSRR, making them attractive for applications that run directly from batteries without regulation.
