The OPA2377 is a low cost, low noise, 5MHz CMOS operational amplifier

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 at a low quiescent current of 0.76mA (typ).

The OPA377 op amp is optimized for low-voltage, single-supply applications. The excellent combination of AC and DC performance makes it ideal for a variety of applications including small signal conditioning, audio and active AD5678BRUZ-1 filters. In addition, these devices have a wide supply range and excellent PSRR, which makes them attractive for applications powered directly from batteries without regulation.
