OPA4377 低成本、低噪声、5.5MHz CMOS 运算放大器

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 (typ).

The OPA377 op amps are optimized for low-voltage, single-supply applications. The exceptional combination of ac and dc performance make them ideal for a wide range of applications, including small signal conditioning, audio, and active filters. In addition, these parts have a wide supply range with excellent PSRR, making them attractive for applications that run directly from batteries without regulation.

The OPA377 is available in the SC70-5, SOT23-5, and SO-8 packages. The dual OPA4377 is offered in the SO-8 and MSOP-8, and the quad OPA4377 in the TSSOP-14 packages
