The OPA377 op amp series is a wide range of bandwidth CMOS amplifiers capable of delivering very low noise, low input bias current and low offset voltage, operating at a low quiescent operating current of 0.76 milliamps (typical).
The OPA377 op amp is optimized for low voltage, single supply applications. The special combination of AC and DC performance makes them ideal for a wide range of applications, including small signal conditioning, audio and active filters. In addition, these devices have an excellent PSRR wide voltage range, making them an immediate attraction for applications that run unregulated batteries.
The OPA377 is available in SC70-5, SOT23-5 and SO-8 packages. The dual OPA2377 offered is available in SO-8 and MSOP-8, and the quad OPA4377 in a TSSOP-14 package.
