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 OPA2377 is offered in the SO-8 and MSOP-8, and the quad OPA4377 in the TSSOP-14 packages. All versions are specified for operation from –40°C to +125°C. CF RF VS OPA377 ...
